+============================
+
+If anyone besides me still has a PowerPC Macintosh, it's no longer
+possible to build gawk using MPFR. C99 and the last version of MPFR
+that works on that platform don't get along, and I could not solve
+the problem. So I simply disabled the MPFR check in configure.ac on
+that platform.
