Thu Mar 14 06:01:07 1996  Roland McGrath  <roland@charlie-brown.gnu.ai.mit.edu>

	* posix/glob.c (glob): In GLOB_BRACE brace expansion, fix buffer size
	calculation to include trailing invariant portion.  Don't use alloca;
	instead use a dynamic auto array for GCC, malloc for non-GCC.
	Handle nested braces properly.

	* elf/elf.h (Elf32_auxv_t): Specify prototype (void) for `a_un.a_fcn'.

	* libc-symbols.h (lint): New macro.

Fri Mar 15 01:18:00 1996  Andreas Schwab  <schwab@issan.informatik.uni-dortmund.de>

	* libio/iosetvbuf.c: Add weak alias setvbuf.
