[Bug math/6778] New: expm1() raises bogus underflow exception for -large

["mtk dot manpages at gmail dot com" <sourceware-bugzilla at sourceware dot org>]

(glibc 2.8)
When expm1(x) is given a large negative x value (e.g., in the range -1e5 through
to -1e308), it correctly returns -1.

However, it also raises an underflow exception.  This is bogus.  The result has
not underflowed: the result is asymptotically close to 1 (not zero).
