Re: Missing routines: gdb/top.c

["John David Anglin" <dave@hiauly1.hia.nrc.ca>]

The module top.c seems to have been corrupted in the most recent
cvs release (19990614).  It appears to be missing procedures such
as init_main.

Well, that was a silly mistake.

I've attached a patch that includes the missing lines of gdb/top.c.
The next snapshot will be correct.c.  I'm not going to fix the CVS
repository, it'll get fixed next Monday when I import the next snapshot.

Thanks for the note,

Jason

This is about to be committed.

1999-06-04  Jim Blandy	<jimb@savonarola.red-bean.com>

	Make the '/c' print format use a true character type.  This is
	more appropriate than builtin_type_char for languages other than
	C, and C tolerates it.
	* gdbtypes.c (builtin_type_true_char): New variable.
	(build_gdbtypes): Initialize it.
	* gdbtypes.h (builtin_type_true_char): New declaration.
	* printcmd.c (print_scalar_formatted): When the format is 'c',
	extract the value as a builtin_type_true_char.
