The configure script reporting unreliable floating-point exceptions
most probably means that the FPE test program couldn't be compiled
on OSX 10.5, which in turn is probably because Apple has seen fit to
make incompatible changes between 10.4 and 10.5.

Someone with access to 10.5 will need to update the FPE test program
embedded in erts/configure.in to work also on 10.5.
