PATCH: for Re: New GCC 3.0 build failure on FreeBSD 4.3

[Loren James Rittle <rittle at latour dot rsch dot comm dot mot dot com>]

Using the same technique already present to hide declarations normally
obtained from OS header files (i.e. low-risk), this patch hides
additional declarations.

These files now build with -Werror (they reported CV qualification
mismatches before).  Full 3.0 bootstrap commencing.

2001-06-11  Loren J. Rittle  <ljrittle@acm.org>

	* strerror.c (sys_nerr): Hide the OS header version.
	* strsignal.c (sys_nsig): Likewise.
