Subject: * sysdeps/ieee754/k_standard.c (__kernel_standard): Pole errors
X-Git-Tag: cvs/fedora-glibc-20090427T1419~21
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=e971e76d8d248ce128641983e90b7cf6e81f2e4e;p=platform%2Fupstream%2Fglibc.git

* sysdeps/ieee754/k_standard.c (__kernel_standard): Pole errors

	for lgamma should se errno to ERANGE, not EDOM.
	* math/libm-test.inc (lgamma_test): Check errno for pole errors.
