Abdel,
I have come up with the attached cygwin.m4, but I am sorry to say
that the -mno-cygwin thing doesn't work when done this way.
Notice that it kicks in when --with-packaging=windows is specified,
as this should be done when using cygwin, otherwise posix would be used.
The point is that -mno-cygwin cannot be seen as flag buth rather
"gcc -mno-cygwin" and "g++ -mno-cygwin" should be considered as
the compilers. So, only when specifying CC='gcc -mno-cygwin' and
CXX='g++ -mno-cygwin' as parameters to configure it works :(
