Whoa, seems I'm the irreproducible-bug-reporter now :-(

Yes:

if ! $srcdir/src/tools/thread/thread_test >&5
then rm -f $srcdir/src/Makefile.global
echo "no"
echo
$srcdir/src/tools/thread/thread_test
echo
AC_MSG_ERROR([Thread test program failed. Your platform is not thread-safe.])
fi

I tried it with:

mkdir /tmp/thr
cd /tmp/thr
~/CVS/pgsql/source/00orig/configure --enable-thread-safety

[lots of output, and then:]
checking for gmake... gmake
checking thread safety of required library functions... Makefile:13: ../../../src/Makefile.global: No such file or directory
gmake: *** No rule to make target `../../../src/Makefile.global'. Stop.
configure: error: Can not clean thread test directory.
