Ok, the problem isn't in axiom and it appears that it isn't in GCL.
I built the same GCL sources (no axiom) on redhat 9 and fedora 5.
The result of
(cos (acos 0.7)) on Redhat is 0.69999999999....96
(cos (acos 0.7)) on Fedora is 0.70000000000...07
so the problem change is likely somewhere in a system library
that gets linked into GCL. Since every other combination of
sins, cos, logs, exps, etc ends up with 0.69999.... I have
to conclude that there is a very minor bug in the Fedora lib.
Anybody happen to know in which system library cos/acos lives?
