You shouldn't do this. That include_next is there to make it as if the files didn't exist. Either provide your own versions of these files in the include path (-I), so the include_next picks them up, or don't include them in the first place: #ifndef _WIN32_WCE #include <errno.h> #endif or, #ifdef HAVE_ERRNO_H #include <errno.h> #endif or similar. > arm-wince-mingw32ce-g++ -DWINCE -D__CLEANUP_C -O3 -finline-functions -shared > -o pthreadGC2.dll attr.o barrier.o cancel.o cleanup.o condvar.o create.o > dll.o errno.o exit.o fork.o global.o misc.o mutex.o nonportable.o private.o > rwlock.o sched.o semaphore.o signal.o spin.o sync.o tsd.o version.o I don't see any libs being linked in here?

Try to find where the 'int errno' is defined as opposed to just declared (extern int errno). Same for _beginthread/_endthread, they should be defined somewhere in the pthreads WinCE port, as WinCE doesn't provide those. > tsd.o:tsd.c:(.text+0x18): undefined reference to `WSAGetLastError' > tsd.o:tsd.c:(.text+0x38): undefined reference to `WSASetLastError' These come from ws2.dll, but you don't have it in the command line...
