Cygwin programs when run by non-cygwin programs do not interpret \" as
an escaped " except within "". This results in errors like the
following when using cygwin gcc in "mingw" mode:
gcc -mno-cygwin -c -s -O2 -DWIN32 -DHAVE_DES_FCRYPT -DPERL_IMPLICIT_CONTEXT -DPERL_IMPLICIT_SYS -fno-strict-aliasing -DPERL_MSVCRT_READFIX -s -O2 -DXS_VERSION=\"0.01\" -DVERSION=\"0.01\" -I"..\..\..\lib\CORE" -I"C:\MinGW\include" -o "lib\Simple.o" "lib\Simple.c"
gcc: no input files
error building dll file from 'lib\Simple.c' at C:\cygwin\home\sthoenna\bleadperl\wp\lib/ExtUtils/CBuilder/Platform/Windows.pm line 143.
The first backslash in -DXS_VERSION=\"0.01\" is treated as a literal
backslash, and the " after it starts a quoted string, resulting in gcc
getting everything after -O2 as a single argument:
-DXS_VERSION=\0.01" -DVERSION="0.01" -I......libCORE -IC:MinGWinclude -o libSimple.o libSimple.c
The following patch fixes this and in theory should not cause any
problems.

Thanks. I've checked this into CVS.

Hi guys,
How come a cygwin issue needs a patch in Windows.pm? Or is this just
a general Windows issue with us doing the shell quoting wrong?

This was a problem with a win32 build using the cygwin compiler in its
mingw cross-compilation mode.
