	point.

Sat Nov  9 02:02:48 1996  Andreas Schwab  <schwab@issan.informatik.uni-dortmund.de>

	* sysdeps/generic/sigset.h: Don't use implicit int which will
	probably require a diagnostic in the next revision of the C
	standard.
	* sysdeps/stub/lockfile.c: Likewise.

Sat Nov  9 01:57:17 1996  Andreas Schwab  <schwab@issan.informatik.uni-dortmund.de>
