Please send GNU C library bug reports via <http://sources.redhat.com/bugzilla/>
using `glibc' in the "product" field.
Version 2.16
* The following bugs are resolved with this release:
13526, 13527, 13528, 13529, 13531, 13532
* ISO C11 support:
+ define static_assert
+ do not declare gets
+ declare at_quick_exit and quick_exit also for ISO C11
+ aligned_alloc. NB: The code is deliberately allows the size parameter
to not be a multiple of the alignment. This is a moronic requirement
in the standard but it is only a requirement on the caller, not the
implementation.
+ timespec_get added
Version 2.15
