	reboot syscall to __syscall_reboot.

	* wcsmbs/wchar.h: Protect prototypes for wcstof and wcstold by
	__USE_GNU, not USE_GNU.

Tue May 21 21:55:49 1996  David Mosberger-Tang  <davidm@AZStarNet.com>

	* locale/programs/charset.c, locale/programs/ld-collate.c:
	Add casts to prevent warnings on 64-bit machines.
