Hi.
I have some problems in thread in W32.
First please analyze my source.

}
in Linux it works successfully, but W32 it’s thread is does not working.
I compiled follow options:
gcc -o drawer.exe
drawer.c -I/gcc-2.95.2/i386-mingw32/include/SDL -lSDL -lgtk-1.3 -lgdk-1.3 -l
glib-1.3 -mno-cygwin -fnative-struct
What is wrong?
