Hi!

The main reason for this problem is that our SCO computer here at TcX
got a hardware problem a while ago and I haven't been able to test the 
latest releases with this.

The fix is to remove the above define from config.h

Could you post directly to me the code in config.log that checks for
pthread_mutex_init.  For some reason, the following code in configure
doesn't work on your SCO machine:

-----------------

  # Check definition of pthread_mutex_init
  echo $ac_n "checking "args to pthread_mutex_init"""... $ac_c" 1>&6
echo "configure:6618: checking "args to pthread_mutex_init"" >&5
if eval "test \"`echo '$''{'mysql_cv_mutex_init_args'+set}'`\" = set"; then
  echo $ac_n "(cached) $ac_c" 1>&6
else
  cat > conftest.$ac_ext <<EOF
#line 6623 "configure"
#include "confdefs.h"
#ifndef SCO
#define _REENTRANT
#endif
#define _POSIX_PTHREAD_SEMANTICS
#include <pthread.h>
int main() {

  pthread_mutexattr_t attr;
  pthread_mutex_t mp;
  pthread_mutex_init(&mp,&attr);
; return 0; }
EOF
if { (eval echo configure:6637: \"$ac_compile\") 1>&5; (eval $ac_compile) 2>&5;
}; then
  rm -rf conftest*
  mysql_cv_mutex_init_args=POSIX
else
  echo "configure: failed program was:" >&5
  cat conftest.$ac_ext >&5
  rm -rf conftest*
  mysql_cv_mutex_init_args=other
fi
rm -f conftest*
fi

echo "$ac_t""$mysql_cv_mutex_init_args" 1>&6
  if test "$mysql_cv_mutex_init_args" = "other"
  then
    cat >> confdefs.h <<\EOF
#define HAVE_NONPOSIX_PTHREAD_MUTEX_INIT 1
EOF
