Do you still see the problems if you link with:
  cc atfork-test.c `glib-config --cflags --libs gthread`

Or equivalently for 1.3:
  cc atfork-test.c `pkg-config --cflags --libs gthread-2.0`

If those cases don't work, then report it as a bug.  Relying on the
dynamic linker to pull in pthread as a dynamic dependency is asking for
trouble.  Various C library functions change behaviour after linking with
pthread (for instance, errno changes).
