[BZ #16364]
* Optimized string, wcsmbs and memory functions for IBM z13.
Implemented by Stefan Liebler.
+* Newly linked programs that define a variable called signgam will no longer
+ have it set by the lgamma, lgammaf and lgammal functions. Programs that
+ require signgam to be set by those functions must ensure that they use the
+ variable provided by the GNU C Library and declared in <math.h>, without
+ defining their own copy.
+
* The minimum GCC version that can be used to build this version of the GNU
C Library is GCC 4.7. Older GCC versions, and non-GNU compilers, can
still be used to compile programs using the GNU C Library.
# The following whitelisted symbols are also allowed for now.
#
-# * Bug 15421: lgamma wrongly sets signgam for ISO C.
-#
# * Bug 17576: stdin, stdout, stderr only reserved with external
# linkage when stdio.h included (and possibly not then), not
# generally.
# * False positive: matherr only used conditionally. matherrf/matherrl are used
# by IA64 too for the same reason.
#
