[PATCH] {,MIN}SIGSTKSZ on IA-64 and SPARC*

[Jakub Jelinek]

Hi!

asm-ia64/signal.h uses 128K/256K and asm-sparc*/signal.h use
4K/16K instead of 2K/8K defined by glibc.

2002-10-01  Jakub Jelinek  <jakub@redhat.com>

	* sysdeps/unix/sysv/linux/ia64/bits/sigstack.h (MINSIGSTKSZ,
	SIGSTKSZ): Changed to match kernel.
	* sysdeps/unix/sysv/linux/sparc/bits/sigstack.h: New file.
