+
+These additional options are available for Microsoft Windows targets:
+
+@table @gcctabopt
+@opindex mconsole
+@item -mconsole
+This option
+specifies that a console application is to be generated, by
+instructing the linker to set the PE header subsystem type
+required for console applications.
+This option is available for Cygwin and MinGW targets and is
+enabled by default on those targets.
+
+@opindex mcrtdll
+@item -mcrtdll=@var{library}
+Preprocess, compile or link with specified C RunTime DLL @var{library}.
+This option adjust predefined macros @code{__CRTDLL__}, @code{__MSVCRT__},
+@code{_UCRT} and @code{__MSVCRT_VERSION__} for specified CRT @var{library},
+choose start file for CRT @var{library} and link with CRT @var{library}.
+Recognized CRT library names for proprocessor are:
+@code{crtdll*}, @code{msvcrt10*}, @code{msvcrt20*}, @code{msvcrt40*},
+@code{msvcr40*}, @code{msvcrtd*}, @code{msvcrt-os*},
+@code{msvcr70*}, @code{msvcr71*}, @code{msvcr80*}, @code{msvcr90*},
+@code{msvcr100*}, @code{msvcr110*}, @code{msvcr120*} and @code{ucrt*}.
+If this options is not specified then the default MinGW import library
+@code{msvcrt} is used for linking and no other adjustment for
+preprocessor is done. MinGW import library @code{msvcrt} is just a
+symlink to (or a copy of) another MinGW CRT import library
+chosen during MinGW compilation. MinGW import library @code{msvcrt-os}
+is for Windows system CRT DLL library @code{msvcrt.dll} and
+in most cases is the default MinGW import library.
+Generally speaking, changing the CRT DLL requires recompiling
+the entire MinGW CRT. This option is for experimental and testing
+purposes only.
+This option is available for MinGW targets.
+
+@opindex mdll
+@item -mdll
+This option is available for Cygwin and MinGW targets. It
+specifies that a DLL---a dynamic link library---is to be
+generated, enabling the selection of the required runtime
+startup object and entry point.
+
+@opindex mnop-fun-dllimport
+@item -mnop-fun-dllimport
+This option is available for Cygwin and MinGW targets. It
+specifies that the @code{dllimport} attribute should be ignored.
+
+@opindex mthreads
+@item -mthreads
+This option is available for MinGW targets. It specifies
+that MinGW-specific thread support is to be used.
+
+@opindex municode
+@item -municode
+This option is available for MinGW-w64 targets. It causes
+the @code{UNICODE} preprocessor macro to be predefined, and
+chooses Unicode-capable runtime startup code.
+
+@opindex mwin32
+@item -mwin32
+This option is available for Cygwin and MinGW targets. It
+specifies that the typical Microsoft Windows predefined macros are to
+be set in the pre-processor, but does not influence the choice
+of runtime library/startup code.
+
+@opindex mwindows
+@item -mwindows
+This option is available for Cygwin and MinGW targets. It
+specifies that a GUI application is to be generated by
+instructing the linker to set the PE header subsystem type
+appropriately.
+
+@opindex fno-set-stack-executable
+@opindex fset-stack-executable
+@item -fno-set-stack-executable
+This option is available for MinGW targets. It specifies that
+the executable flag for the stack used by nested functions isn't
+set. This is necessary for binaries running in kernel mode of
+Microsoft Windows, as there the User32 API, which is used to set executable
+privileges, isn't available.
+
+@opindex fno-writable-relocated-rdata
+@opindex fwritable-relocated-rdata
+@item -fwritable-relocated-rdata
+This option is available for MinGW and Cygwin targets. It specifies
+that relocated-data in read-only section is put into the @code{.data}
+section. This is a necessary for older runtimes not supporting
+modification of @code{.rdata} sections for pseudo-relocation.
+
+@opindex mpe-aligned-commons
+@item -mpe-aligned-commons
+This option is available for Cygwin and MinGW targets. It
+specifies that the GNU extension to the PE file format that
+permits the correct alignment of COMMON variables should be
+used when generating code. It is enabled by default if
+GCC detects that the target assembler found during configuration
+supports the feature.

-is for Windows system CRT DLL library @code{msvcrt.dll} and
-in most cases is the default MinGW import library.
-Generally speaking, changing the CRT DLL requires recompiling
-the entire MinGW CRT. This option is for experimental and testing
-purposes only.
-This option is available for MinGW targets.
-
-@opindex mdll
-@item -mdll
-This option is available for Cygwin and MinGW targets. It
-specifies that a DLL---a dynamic link library---is to be
-generated, enabling the selection of the required runtime
-startup object and entry point.
-
-@opindex mnop-fun-dllimport
-@item -mnop-fun-dllimport
-This option is available for Cygwin and MinGW targets. It
-specifies that the @code{dllimport} attribute should be ignored.
-
-@opindex mthreads
-@item -mthreads
-This option is available for MinGW targets. It specifies
-that MinGW-specific thread support is to be used.
-
-@opindex municode
-@item -municode
-This option is available for MinGW-w64 targets. It causes
-the @code{UNICODE} preprocessor macro to be predefined, and
-chooses Unicode-capable runtime startup code.
-
-@opindex mwin32
-@item -mwin32
-This option is available for Cygwin and MinGW targets. It
-specifies that the typical Microsoft Windows predefined macros are to
-be set in the pre-processor, but does not influence the choice
-of runtime library/startup code.
-
-@opindex mwindows
-@item -mwindows
-This option is available for Cygwin and MinGW targets. It
-specifies that a GUI application is to be generated by
-instructing the linker to set the PE header subsystem type
-appropriately.
-
-@opindex fno-set-stack-executable
-@opindex fset-stack-executable
-@item -fno-set-stack-executable
-This option is available for MinGW targets. It specifies that
-the executable flag for the stack used by nested functions isn't
-set. This is necessary for binaries running in kernel mode of
-Microsoft Windows, as there the User32 API, which is used to set executable
-privileges, isn't available.
-
-@opindex fno-writable-relocated-rdata
-@opindex fwritable-relocated-rdata
-@item -fwritable-relocated-rdata
-This option is available for MinGW and Cygwin targets. It specifies
-that relocated-data in read-only section is put into the @code{.data}
-section. This is a necessary for older runtimes not supporting
-modification of @code{.rdata} sections for pseudo-relocation.
-
-@opindex mpe-aligned-commons
-@item -mpe-aligned-commons
-This option is available for Cygwin and MinGW targets. It
-specifies that the GNU extension to the PE file format that
-permits the correct alignment of COMMON variables should be
-used when generating code. It is enabled by default if
-GCC detects that the target assembler found during configuration
-supports the feature.
