Comment (by rogerdpack):

 My latest guess is that configure does this test compile:
 {{{
 extern int pthread_create();
 int main(void){ pthread_create(); }
 }}}

 then compiles it like $ gcc -c input_filename -o output.o

 which happily creates output.o (but output.o would fail at link time since
 libpthread.a library is absent).

 I believe my initial report was reporting that I had configured it without
 passing the right compiler directive flags to *use* libpthread.a
 correctly, the second report was when I had no libpthread.a file present
 on the system at all. So that's why the 2 messages differ--they both had
 broken pthread libraries (or absent), but they were broken in slightly
 different ways.
 HTH.
