d1fcfd1939 Implement --traditional so qfcc can be a nicer qcc. This disables several
keywords (quaternion integer function for break continue switch case default
NIL struct enum typedef) and converts some errors to warnings (assignment to
constants, insufficient function arguments, return; from non-void function,
anal function `pointer' type checks)

29c68732c0 More Forge stuff.
Forge now loads the bundles in its resources first, and then loads the
bundles from the User, Local, Network, and System library directories,
in that order -- if it is told to by the defaults system.

Also, the MainPrefs class has some new options, to control what
directories Forge loads bundles from.
2002-01-26 22:09:15 +00:00
Jeff Teunissen
8ef321e2e8 Forge updates -- an icon for .forge files, some app info updates, and a
nib-loading fix for MainPrefs.
2002-01-26 05:13:25 +00:00
Jeff Teunissen
9585b6af92 Forge updates. Preferences is no more, since each bundle will have its
own prefs anyway. The "sample" bundle MainPrefs is more complete, and is
now loading its interface from a .gorm file -- this would be a .nib on
NeXTstep or Mac OS X, and it should be ready to run on those OSes
already -- since it doesn't do much. :)

8a24b28d97 scary, but the only changes qfcc needed to build as part of quakeforge was
to auto-substitued the libs and headers.

 o  unconditionally build qfcc (for now, anyway) when building quakeforge
    (needed for cs-code compilation)
 o  when built as part of quakeforge (qfcc should still be buildable
    independently) always enable cpp
 o  autoconfiscate the client-side code
 o  build the client-side code using the built qfcc
 o  install the client-side code in $(datadir)/quakeforge/id1

f2f8e096f3 qfcc.h:
o	add a "freed" marker to def_t to prevent double freeing of
		temp def offsets
emit.c:
	o	break out the bind code into emit_bind_expr (doesn't /really/
		emit code, but still:)
	o	make bind work with disparate types (forces def_t->freed 1)
pr_def.c:
	o	mark array pointers as initialized and constant.
	o	don't free the offset for already freed temp defs
pr_imm.c
	o	fix a bug in uinteger support
	o	support disparate types for immediates
switch:
	o	fix a bug where gt.i was being used instead of gt.ui
	o	remove some debug code

eb7d41b95c Fix for configure to give it a zlib check, just like qfcc. qfdefs now compiles
again statically.

But I'm sure taniwha is going to fix that shortly anyway :)

9f1f89f8f1 Forge: New -- a preferences panel. Doesn't do anything yet, but that's
only because I haven't created the main prefs view class yet. Trust me,
it's going to work. I think. :)

Anyway, what code there is works, and is linked into the menu -- just
hit Info -> Preferences... to see it.

643aa795d6 fill the bsb and brush menus with a "dunno" filler that just, er, selects
"undo" for now. This is so Controller.m compiles on my system (using gcc 3)
