@c This is part of the GCC manual.
attribute also implies ``default'' visibility. It is an error to
explicitly specify any other visibility.
-Currently, the @code{dllexport} attribute is ignored for inlined
-functions, unless the @option{-fkeep-inline-functions} flag has been
-used. The attribute is also ignored for undefined symbols.
+In previous versions of GCC, the @code{dllexport} attribute was ignored
+for inlined functions, unless the @option{-fkeep-inline-functions} flag
+had been used. The default behaviour now is to emit all dllexported
+inline functions; however, this can cause object file-size bloat, in
+which case the old behaviour can be restored by using
+@option{-fno-keep-inline-dllexport}.
+
+The attribute is also ignored for undefined symbols.
When applied to C++ classes, the attribute marks defined non-inlined
member functions and static data members as exports. Static consts
of assembly instructions and as such its exact meaning might change from one
release to an another.
+@item -fno-keep-inline-dllexport
+@opindex -fno-keep-inline-dllexport
+This is a more fine-grained version of @option{-fkeep-inline-functions},
+which applies only to functions that are declared using the @code{dllexport}
+attribute or declspec (@xref{Function Attributes,,Declaring Attributes of
+Functions}.)
+
@item -fkeep-inline-functions
@opindex fkeep-inline-functions
In C, emit @code{static} functions that are declared @code{inline}
