Re: Patch for isdigit/isalpha/etc. macro arguments

[Steve Ellcey <sje@cup.hp.com>]

Well, this discussion was very interesting but I am not sure it led
anywhere.  If casting to '(int)' is unacceptable, double casting to
'(int) (unsigned char)' is probably even less acceptable so I would like
to check in the following patch that turns off the warnings so I can
build on HPPA HP-UX.

Tested by building on HPPA HP-UX.

OK to checkin?

	* configure.ac (build_warnings): Add -Wno-char-subscripts.
	* doc/gdbint.texinfo (warning flags): Add -Wno-char-subscripts.

 These are warnings which might be useful for @value{GDBN}, but are
 currently too noisy to enable with @samp{-Werror}.
