Fix the line number info for else.
...
It has bugged me for a while that the goto for else would display the if's
source line.

Rework the unary_expr grammar to allow ++*foo.
...
This required throwing out the primary rules that snax did up to help me
with conflicts many years ago, but they were now getting in the way. Now
the productions from primary are merged in with unary_expr.

Fix the bogus missing return warning.
...
Pascal's return mechanism is such that void return is always used.

Add the COMMA token to the pascal parser.
...
I guess I forgot I needed to keep token numbers in sync between pascal and
qc/ruamoko.

Delay storage setting for pascal functions.
...
The function def must not be local. This fixes the null function call in
gcd.pas.

Call find_type for pascal functions/procedures.
...
The result of parse_params needs to be passed through find_type before
actually being used. I guess I'd missed this back when I got things working
for qc.

Merge qfpc into qfcc.
...
Since gnu bison and flex are required anyway, no harm in using their api
prefix options. Now, qfcc can compile both QC/Ruamoko and Pascal files
(Pascal is (currently?) NOT supported in progs.src mode), selecting the
language based on the extension: .r, .qc and .c select QC/Ruamoko, .pas and
.p select Pascal, while anything else is treated as an object file (as
before).

Move method function defs into the far data space.
...
As they are never referenced directly by instructions, there's no need for
them to be in the near data space, taking precious def locations.

Get qfcc running again.

It segs when it tries to link, but that's because a real object file has
not been created yet. However, I can get my tree and flow diagrams :)

Even more FIXMEs, but the pascal parser can now create functions. The

Rewrite much to use symbols and symtabs. Gut emit.c. Massive breakage.
...
That which isn't rewritten is horribly broken. However, this does include a
nice mechanism for building QC structs for emitting data.
emit.c has been gutted in the spirit of "throw one away".
There is much work to be done to get even variables emitted, let alone
code. Things should be a little more fun from here on.

Rework the lexer and parser to use symbols instead of defs.

Currently parses the test program just fine, but code generation is very
very broken.

Make QuakePascal programs runnable.

Generate a mini-main function (".main", to avoid namespace pollution) that
calls the function named by "program", and make qwaq check for ".main" as
well as "main". If both are present, ".main" will take priority.

extensions. There is already work on the type system.
