Subject: 2.053 fails to build on strawberry perl (MS Windows) 5.14.2
The failure is:

cp lib/Compress/Raw/ blib\lib\Compress\Raw\
AutoSplitting blib\lib\Compress\Raw\ (blib\lib\auto\Compress\Raw\Zlib)
Z:\strawberry32\perl\bin\perl.exe Z:\strawberry32\perl\lib\ExtUtils\xsubpp  -typemap Z:\strawberry32\perl\lib\ExtUtils\typemap -typemap typemap  Zlib.xs > Zlib.

In file included from adler32.c:8:
./zlib-src/zutil.h:37: error: conflicting types for 'ptrdiff_t'
z:\strawberry32\c\bin\../lib/gcc/i686-w64-mingw32/4.4.7/../../../../i686-w64-mingw32/include/_mingw.h:390: note: previous declaration of 'ptrdiff_t' was here
dmake:  Error code 129, while making 'adler32.o'

The problem is in zutil.h:
#ifdef Z_SOLO
   typedef long ptrdiff_t;  /* guess -- will be caught if guess is wrong */

after commenting out this typedef the build succeeds

so the patch could be:

#if defined(Z_SOLO) && !defined(__MINGW32__)
   typedef long ptrdiff_t;  /* guess -- will be caught if guess is wrong */

Thanks - reproduced the issue here. Paul
