Update.
1999-09-24 Andreas Jaeger <aj@suse.de> * stdio-common/tst-printf.c (main): Add a testcase for large precision. Reported by Tymm Twillman <tymm@coe.missouri.edu>. 1999-09-24 Andreas Schwab <schwab@suse.de> * math/bits/mathcalls.h: Fix last change. Also declare __finite. 1999-09-24 Andreas Jaeger <aj@suse.de> * intl/finddomain.c (_nl_find_domain): Fix memory leak: Free normalized_codeset. Reported by Belicky Zsolt <zsolt@prolan.hu>. 1999-09-23 Mark Kettenis <kettenis@gnu.org> * sysdeps/unix/sysv/linux/Makefile [malloc] (CFLAGS-malloc.c): New variable. Define MORECORE_CLEARS to 2. * malloc/malloc.c (cALLOc): Correctly handle systems where sbrk doesn't clear the contents of memory that is reallocated after decrementing the break value first. Update comment about MORECORE_CLEARS, explaining the meaning of the values it can be set to.

MORECORE_FAILURE (default: -1)
The value returned upon failure of MORECORE.

- holds for sbrk).
+ The degree to which the routine mapped to MORECORE zeroes out
+ memory: never (0), only for newly allocated space (1) or always
+ (2). The distinction between (1) and (2) is necessary because on
