Patch: --enable-profiling

[Tom Tromey <tromey at cygnus dot com>]

This patch adds a `--enable-profiling' option to gdb's configure
script.  If given, this defines ENABLE_PROFILE and builds gdb with
`-pg'.  ENABLE_PROFILE adds a new maintenance command which can be
used to enable or disable profiling from the command line.  (By
default profiling is turned off in main()).

Ok to check in?

1999-10-29  Tom Tromey  <tromey@cygnus.com>

	* config.in: Rebuilt.
	* acconfig.h (ENABLE_PROFILE): New #undef.
	* Makefile.in (PROFILE_CFLAGS): New macro.
	* configure: Rebuilt.
	* configure.in: Added --enable-profiling.  Define ENABLE_PROFILE
	if provided.  Set and subst PROFILE_CFLAGS.
	* maint.c (maint_moncontrol): New function.
	(_initialize_maint_cmds): Add `moncontrol' command if profiling
	support is enabled.
	* main.c (main): Turn off profiling if profiling support is
	enabled.
