[TCLCORE] Re: --enable-gcc is dead!

Weird - I always seemed to get what I wanted out of any configure by
setting the CC variable (and the CCC variable when setting the C++ compiler).

A few notes for configure writers :
	If you activate an enable flag, PLEASE activate a disable flag!
		That was my only gripe about the enable-gcc flag.

	If you activate other specialty flags, indicate clearly in the help
		whether the flag is a boolean (with the option to indicate
		the negative as well) or indicate what specifically the flag
		is wanting indicated *by example* .  I've seen --help
		output which sometimes wants you to specify --with-stuff
		as a boolean, sometimes with an add-on value --with-other=stuff.

	If you need a directory, indicate by example where in the tree you
		want.  Sometimes extentions want the top of the source tree,
		sometimes they want the top of an installation directory
		(which may NOT be the top of the Tcl installation directory!),
		and sometimes they want some subdirectory in one of these.

	If your extension is installing binary components, be sure to check
		the exec-prefix for configure for the path where the user
		wants binaries installed.

	If your extension is purely tcl, give the user the option of installing
		a symlink or provide a shell wrapper that points to the real
		source directory.  That provides an easier way to move between
		releases...
