I have applied this patch to the gcc-3.4 branch to fix a FreeBSD problem
with computing __LDBL_MAX__.  This occurs because FreeBSD uses a
non-default x86 FP format (53-bits fraction in long double), and the
default FP format did not get overridden properly when preprocessing but
not compiling.  This is a backport of a patch I added to mainline about
two weeks ago.

This was tested with a gcc-3.4 bootstrap on an x86 FreeBSD 4.7 machine,
with a make check.  There were no regressions.
