(svn r7796) -Fix (r7759): cygwin does not need to rewrite the paths for strgen.
-Fix (r7759): supply the correct flags to cygwin to make it compile.

Note: cygwin itself is 'broken'. Known issues with cygwin are:
- bash does not work when including files that have dos line ending (\r\n).
This causes the strange errors in config.lib. The solution is running:
dos2unix config.lib
- the windows-native svn does not work (though it previously did). The
solution for this is to install the cygwin svn.
- libfreetype2's freetype-config --cflags does not have ft2build.h in the
path include search path. The workaround for this is to copy
/usr/include/ft2build.h to /usr/include/freetype2/. Also linking does
not work for static builds as freetype-config does not support that.
You have to add the '--disable-static' flag when running './configure'.
- libpng12 does not work with static building either. You have to add
the '--disable-static' flag when running './configure' too.
