The errors are different because acosh are used differently in those two
Try removing `#if !defined(HAVE_INVERSE_HYPERBOLIC)` block from
fastumath_unsigned.inc. This should ensure that acosh, etc are defined.
If that still does not work then resend build.log to me. May be I can find
there something off..

gcc version 2.95.4 20011002 (Debian prerelease)
and it works fine on a Debian box.
