Hi!
I know it's late for the release, but I'd like to squeeze this one in
too, if at all possible. After all, it doesn't affect anything but MSVC.
With the patch, I get
sys_lib_search_path_spec="/c/PROGRA~1/MID05A~1/VC/ATLMFC/LIB
/c/PROGRA~1/MID05A~1/VC/LIB /c/PROGRA~1/MID05A~1/VC/PLATFO~1/lib
/c/PROGRA~1/MID05A~1/SDK/v2.0/lib"
on MSYS/MSVC, and
sys_lib_search_path_spec="/cygdrive/c/PROGRA~1/MID05A~1/VC/ATLMFC/LIB
/cygdrive/c/PROGRA~1/MID05A~1/VC/LIB
/cygdrive/c/PROGRA~1/MID05A~1/VC/PLATFO~1/lib
/cygdrive/c/PROGRA~1/MID05A~1/SDK/v2.0/lib"
on Cygwin/MSVC, which is a whole lot better than what was there before,
namely this for both
sys_lib_search_path_spec="C:\Program Files\Microsoft Visual Studio
8\VC\ATLMFC\LIB C:\Program Files\Microsoft Visual Studio 8\VC\LIB C:\Program
Files\Microsoft Visual Studio 8\VC\PlatformSDK\lib C:\Program Files\Microsoft
Visual Studio 8\SDK\v2.0\lib"
which simply isn't any good at all.
If this patch is included it means that I can remove tiresome workarounds
when linking with system libraries.
This needs testsuite exposure, and search-path.at seems to come close,
but is not up to the task. Not even if I extend it to try some other
"system library" such as -luser32 if -lz isn't found.
So, ok to push even if it's late and without testsuite coverage?
Cheers,
Peter

Subject: [PATCH] msvc: eliminate spaces in the library search path.
* libltdl/m4/libtool.m4 (_LT_SYS_DYNAMIC_LINKER) [mingw, cygwin]
<cl*, sys_lib_search_path_spec>: The LIB path variable telling
where MSVC looks for libraries is with high probably containing
directory names with spaces. Convert those directory names to
the short 8.3 dos form (i.e. without spaces) when storing them
in sys_lib_search_path_spec, as that is a space separated
variable.
