+# Hack warning: gmplib is built separately in 32-bit and 64-bit mode
+# and then merged afterwards.  Somehow, gmplib's header files appear
+# to be dependant on the CPU architecture on which configure was
+# run. Not nice, but as long as we also build mpfr in two separate
+# steps and nobody else uses these architecture-dependent macros, we
+# should be fine.
