alternative patch

I think the intent of AC_LANG_PROGRAM here was to test for linking validity by
making sure that a pointer to the gnutls_mac_get_key_size() function would be
usable at runtime. The patch in comment #1 replaces this test with something
fundamentally different: a test for a type definition that matters only at
compile time.

I therefore think the patch I am attaching would be a better solution.
