That patch looks much better.  One thing, though: do we really want to bother
with AC_CHECK_FUNCS at all?  What advantage does that give us over just using
AC_TRY_LINK?  Using AC_TRY_LINK alone would mean we don't have to consider
platform-specific details about the implementation of pthread functions (at
least, on platforms which *do* provide pthread stubs).

Also, have you tested that the appropriate HAVE_* macros get set in the
AC_TRY_LINK case, so that the appropriate stubs go into the library?
