Actually, it's an i386-specific gcc bug in the parsing of
hexadecimal floating-point constants.  I have a good idea of which
change between gcc 3.3 and 3.4 broke it, but it looks like it will
be difficult to get a gcc developer to investigate.  This is
because it only happens on platforms that have an extended
precision long double format but only double precision evaluation,
and FreeBSD/i386 is the only platform like that.
