Hi list, this is my first post here.
I'm writing an application that uses SDL, lib3ds and glib
I've installed SDL and lib3ds from sources, both compiled with 
-mno-cygwin, while glib (2.2) comes from here
I wasn't able to compile it from sources, still need to understand why.
Anyway after I actually compiled my application I run it and ... SIGSEGV
(The application works in my linux box)
With gdb I was able to collect this stack trace:

Program received signal SIGSEGV, Segmentation fault.
0x61021a8b in unsetenv () from /usr/bin/cygwin1.dll

#10 0x004073df in main ()

I tried to get cygwin from cvs and compile a debug version of 
cygwin1.dll, but i can't.
I didn't find a doc on how to compile it from sources, in particular i'm 
interestend in compiling only src/winsup/cygwin and not all cygwin.
Is it possible? How?
If i can compile it I'll able to understand where's the problem
