History
Joseph Myers ce9c5b3e95 Fix ldbl-128 expm1l spurious underflow (bug 16539). 
This patch fixes spurious underflows from ldbl-128 expm1l, as reported
in <https://sourceware.org/ml/libc-alpha/2014-06/msg00835.html> and
exposed by the tests added for such a bug in the x86 / x86-64
version.  The bug and fix are essentially the same, so no separate bug
is filed in Bugzilla.

Tested for mips64.

	[BZ #16539]
	* sysdeps/ieee754/ldbl-128/s_expm1l.c: Include <float.h>.
	(__expm1l): Return argument unchanged when small but not
	subnormal.
