[issue1682] math.h constants, aren't constant

["Stathis Kamperis \(via DragonFly issue tracker\)" <sinknull@xxxxxxxxxxxxxxxxxxxxx>]

New submission from Stathis Kamperis <ekamperi@gmail.com>:

According to C99, HUGE_VAL, HUGE_VALF, HUGE_VALL, INFINITY, and NAN need to be
constant expressions. We use some gcc __builtin() call when defining them, which
violates the standard.

Test case to reproduce it:
http://gitweb.dragonflybsd.org/~beket/pcca-tests.git/blob_plain/master:/math.h/t_const.c

NetBSD is affected as well. FreeBSD + Opensolaris not.

Cheers,
Stathis
