I think you didn't understand me.

I mean not to integrate your library into GCC as real separate library.
I mean to do changes on 
config/i386/gthr-win32.h+config/i386/gthr-win32.c+config/i386/gthr-win32-cond.c 
etc using your code to have an implementation of everything needed for 
C/C++ threads on Windows.

got it...
anyway it seems logical to me the way I proposed :)


best!
