c68578d15d Rename CONST to VALUE.
VALUE is a much more accurate name, and this allows for "const" to be
implemented at some stage.

5725c5124c Rename the storage_class_t enum values.
With the intoduction of the statement type enum came a prefix clash. As
"st" makes sense for "statement type", I decided that "storage class"
should be "sc". Although there haven't been any problems as of yet, I
decided it would be a good idea to clean up the clash now. It also helps
avoid confusion (I was a bit surprised after working with st_assign etc to
be reminded of st_extern etc).

54289da416 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.

f307c7bebc 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.

7519ec7bbd Fix the bogus missing return warning.
Pascal's return mechanism is such that void return is always used.

52b9721027 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.

72045f1a5b Delay storage setting for pascal functions.
The function def must not be local. This fixes the null function call in
gcd.pas.

5530e84ada 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.

f14d8060e0 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).

bc1b483525 Nuke the rcsid stuff.
It's pretty useless in git.

4336fc2c73 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.

54c14eb899 Add "return" to pascal.
I'm still not sure I'll keep it, but it's useful for testing.

7e914b8c53 Fix copyright headers.
Add forgotten templates and fill in the information in places I had
forgotten. I hope I got the dates right (timezone issues).

4ac80c2932 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 :)

However, the statements are only printed as expressions.

87ce9f5333 Get basic function creation working.
Even more FIXMEs, but the pascal parser can now create functions. The
function records even get emitted.

ea3895805b 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.

fb8b3d1211 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.

3c9991364b Add a "void return" instruction.
I got fed up with always having to explicty return something.

Already extending QuakePascal, and many basics aren't there yet :P

02b3dde83b 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.

This is a nasty commit, sorry, but 99% of the commit is interdependent.

No actual code is emitted, though.

fed82466cc The first stages of Quake-Pascal.
At present, this parses a subset of the pascal language with a few type
extensions. There is already work on the type system.
