Why did Callback.dll fail to build? Other than the 32 to 64 cast
warnings, I dont see anything else in the compiler log.

WC_NO_BEST_FIT_CHARS is defined in Cygwin
http://cygwin.com/cgi-bin/cvsweb.cgi/src/winsup/w32api/include/winnls.h?rev=1.10&content-type=text/x-cvsweb-markup&cvsroot=src
in a WINVER conditional and it also is in a WINVER conditional on Visual
C. But Win32:: has
___________________________________________________
#ifndef WC_NO_BEST_FIT_CHARS
#  define WC_NO_BEST_FIT_CHARS 0x00000400
#endif
___________________________________________________
in it. Strawberry does not keep WC_NO_BEST_FIT_CHARS in a conditional
http://mingw-w64.svn.sourceforge.net/viewvc/mingw-w64/trunk/mingw-w64-headers/include/winnls.h?revision=5147&view=markup
. I'll guess Cygwin Perl does not set WINVER but native Win32 Perl does.

Strawberry defines __int3264 in
http://mingw-w64.svn.sourceforge.net/viewvc/mingw-w64/trunk/mingw-w64-headers/include/basetsd.h?revision=5316&view=markup
and __int32 in
http://mingw-w64.svn.sourceforge.net/viewvc/mingw-w64/trunk/mingw-w64-headers/crt/_mingw.h.in?revision=5431&view=markup
. Cygwin defines __int3264 in
http://cygwin.com/cgi-bin/cvsweb.cgi/src/winsup/w32api/include/basetsd.h?rev=1.6&content-type=text/x-cvsweb-markup&cvsroot=src
but I dont have Cygwin's headers to grep to see if __int32 is defined. I
think I will try INT_PTR instead of __int3264.

Getting Win32::API working on your 32 bit with quads Cygwin will take a
couple trys since once it compiles, I bet a 32 bit with 64 ivs bug will
come up. Can you try my github version (not right now, no changes are up
right now) at https://github.com/bulk88/perl5-win32-api in the future as
part of this ticket? IDK if Cosimo has time to make new CPAN releases
which may or may not work on Cygwin, and I really wouldn't want
Win32::API to hit 1.00 any time soon.
