I downloaded pth207.b from the DJGPP beta directory. For a test I
tried to compile this program, which I took from a "configure" file:

#include <pthread.h>
int
main ()
{
pthread_create(0, 0, 0, 0);
  ;
  return 0;
}

./configure tells me this fails and when I try to compile this
program, named thread.c, with this command:

gcc -o thread.exe thread.c -lpthread

I get the following errors:

e:/djgpp/lib/libpthread.a(pth_high.o):pth_high.c:(.text+0x211):

e:/djgpp/lib/libpthread.a(pth_high.o):pth_high.c:(.text+0x269):

collect2: ld returned 1 exit status

What shall I do to get this to compile? I also tried the version in
the current directory but that showed even more undefined references.
