Hi Pedro,
thanks for the hints, I got libpthread compiling now. Since __MINGW32__ is
defined, the code assumes some things that are not true for WinCE, e.g. like
having errno. Instead of modifying mingw32ce now I just modify the
pthread-w32-2.8.0 code and add a few more compiler flags, see the attached diff
file. I compile with
make CROSS=arm-wince-mingw32ce- CC="arm-wince-mingw32ce-g++ -DWINCE
-DNEED_ERRNO -D_ARM_ -D__CRTDLL__ -D_DLL" clean GC
PS: I still can't compile jamvm because of missing liltdl. Do you know where I
can find it for WinCE? It seems to be part of glibc...
Kind Regards,
Leonardo.

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.

I don't see any libs being linked in here? Where is the -lws2 ?

Looks like you are missing some .o's in the link command line. 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.

These come from ws2.dll, but you don't have it in the command line... (-lws2)
Cheers,
