Thanks.  We're using the following more-general patch instead.

2004-02-09  Paul Eggert  <address@hidden>

        * lib/autoconf/fortran.m4 (_AC_FC_LIBRARY_LDFLAGS): Ignore all
        flags of the form -lcrt*.o, not just -lcrt[01].o and -lcrtbegin.o.
        Darwin uses -lcrt2.o and there's little point to cataloging all
        the system variants.  Partial fix reported by Andreas Waechter in:
