libtool: Support MSYS and MSYS2 file path conversions
MSYS does not have cygpath installed by default, so during configure,
a check for cygpath is cached. If cygpath is not found, Window's command

"cmd //c".

On MSYS2, file path conversion will no longer result in libtool hanging,
but the original MSYS will not be able to do file path conversions
without cygpath. Original MSYS support for file path conversions will be
re-added before commit 1377b68b4aed0d6ee3c390131eb763d26e5b642d migrates

When building libltdl with the MSVC toolchain, Fortran checks can cause

Fortran compiler environment variables to "no".

libtool: Fix MSVC cl.exe .exp extension collision
MSVC's compiler uses the .exp entension for their own export format,
which causes a build failure when a subsequent build is run. The
MSVC compiler, cl.exe, errors for an invalid file format. This is fixed
by using a similar extension name to avoid the naming collision.
Translating file paths from MSYS to W32 has been causing libtool to
indefinitely hang when 'cmd.exe //c' is called. Instead, 'cygpath' is
packaged on MSYS, so it will now handle the path conversion.
* build-aux/ltmain.in: Replace 'cmd.exe //c' with 'cygpath' usage.

libtoolize.in: Create symlinks with mklink for MSVC
Symlink files are not generated properly with 'ln -s' for MSVC to
process, so mklink is used, which swaps the argument order of target

use of cygpath.
* libtoolize.in: Check if linking with mklink and update processing.
When comparing expected output in LT_AT_CHECK_EXECUTE, several tests
fail with mismatched line endings. This patch should fix Windows
environments that have CRLF text line endings disabled and only use
the LF character for line endings.
* tests/testsuite.at: Removed '\r' from awk's printf command.
libtool: Fix mishandling compiler flags with MSVC tools

ltmain.in: Supporting -S and -t flags from install-sh
Libtool silently discards options for install-sh that have not been

The documentation follows the traditional method of inserting newlines
before the 80 character limit, with a few exceptions. Now, the
documentation will use some semantic newlines, specifically inserting
newlines for clause breaks (commas, semicolons, colons, and so on).
However, it will only break on symbols, instead of also breaking for
phrases, and it will still utilize the 80 character limit should a
symbol break not exist first.

ltoptions.m4: Make aix-soname assignment more clear
The option --with-aix-soname=svr4 does not work the same as using
LT_INIT([aix-soname=svr4]), since the configure script is reordered
depending on which is used. The reordering causes 'enable_shared'
to not be set before processing for 'aix-soname' when using LT_INIT.

be set before 'aix-soname=svr4', like LT_INIT([shared aix-soname=svr4]).
