I don't understand what do you want to show with that exmaple ? Please, 
give more details. _WIN32 is not defined on Cygwin, so "gswin32c.exe" 
should not be picked up if everything is set up correctly. See below the 
output of gcc -v on Cygwin:

Reading specs from /usr/lib/gcc-lib/i686-pc-cygwin/2.95.3-5/specs

sizeof.c /tmp/ccBFlJvZ.i

Please, explain which features are available only if _WIN32 is defined ? 
Cygwin is a POSIX emulation layer - so what compiles on POSIX compliant Unix
system should compile on Cygwin too (most of the time :) ).

I'm not convinced about the libpng issue , but anyway this is not a 
showstopper IMO.

Yes - only runtime dependencies.

I'll wait for your answer on the compilation details before reviewing 
that.
