I think I wrote what I want to do the wrong way.
I want to build a cross compiler on linux that would output Cygwin
executables ( Linux host -> Cygwin target).
I tryed crosstool and while building on linux with script
demo-cygwin.sh I get:
i686-pc-cygwin-ranlib libmingwex.a
make[3]: Leaving directory

I downloaded w32api-3.8-1-src.tar.bz2 package but now I don't know
what to do with it.
Anny suggestions?
