ccaa4ad3d2 [qfcc] Catch assignment of void* to class pointers
id and other class pointers imply that the object can receive messages,
but void * has no such implication, so treat it as a mismatch.

65a5e4f2a4 [qfcc] Allow inherited methods to satisfy protocols
I suspect that the current state of things will produce problems later
on, but this works for now.

1459361cbd [qfcc] Set builtin function def flags
This fixes the missing redefinition error when a builtin is defined
twice (and thus corrupting the function chain).

9ccfe8aefc [qfcc] Rewrite init_elements
The end goal was to fix erroneous non-constant initializer errors for
the following (ie, nested initializer blocks):

    typedef struct { int x; int y; } Point;
    typedef struct { int width; int height; } Extent;
    typedef struct Rect_s { Point offset; Extent extent; } Rect;
    Rect makeRect (int xpos, int ypos, int xlen, int ylen)
    {
	Rect rect = {{xpos, ypos}, {xlen, ylen}};
	return rect;
    }

However, it turned out that nested initializer blocks for local
variables did not work at all in that the relocations were lost because
fake defs were being created for the generated instructions.

Thus, instead of creating fake defs, simply record the offset relative
to the base def, the type, and the basic type initializer expression,
then generate instructions that all refer to the correct def but with a
relative offset.

Other than using the new element system, static initializers are largely
unaffected.

f3236410d0 [qwaq] Make the event system more informative
Doesn't have timestamps at this stage, but otherwise it reflects the
event system I had in my old text UI which was heavily based on
TurboVision. TV is pretty good (after looking at things a bit closer I
found it wasn't as deep as I thought), and better yet, Borland released
it to the public domain 23 years ago! (wish I'd known that).

Anyway, this commit gets something happening on the screen, even though
the current hierarchy is still a mess.

f532780dbe [qfcc] Treat opaque structs as not anonymous
I don't know why the segfault happened where it did, but
forward-declared structs certainly can't be used as anonymous structs.

4fa203852a [qfcc] Use offset alias offset when creating alias of offset alias
Yes, that's correct. It happens when casting the address of a structure
field (for the test case this fixes, vector field).

de01cff70e [build] Install QF/keys.h into qfcc's include directory
As well as $prefix/include, of course. This fixes the problem with
external ruamoko builds failing due to keys.h and qfcc's "lockdown" on
system headers.

c58cf2c2d0 [qwaq] Fail at object oriented design 101
This is horrible, doesn't work, isn't really the direction I want to go
(that became apparent while implementing Screen's handleEvent) and
crashes anyway (Array and not-id...)

*sigh*

Still, this does have some good stuff in it, and it pushed qfcc along
some more.

ed04e6fc23 [qfcc] Merge method lists instead of copying
This is for adding methods to classes and protocols via their interface,
not for adding methods by adding protocols (they still get copied).
Slightly more memory efficient.

f025bd96d4 [qfcc] Copy self param when copying methods
Copying methods is done when adding protocols to classes (the current
use for adding regular methods is an incorrect solution to a different
problem). However, when a method is added to a class, the type of its
self parameter is set to be a pointer to the class. Thus, not only does
the method need to be copied, the self parameter does too, otherwise
the self parameter of methods added via protocols will have their type
set to be a pointer to the last class seen adding the protocol.

That is, if, while compiling the implementation for class A, but the
interface for class B is comes after the interface for class A, and both
A and B add protocol P, then all methods in protocol P will have self
pointing to B rather than A.

@protocol P
-method;
@end

@interface A <P>
@end

@interface B <P>
@end

@implementation A
-method	{} // self is B, not A!
@end

f6d650d473 [qfcc] Merge duplicate methods in interfaces
Duplicate methods in an interface (especially across protocols and
between protocols and the interface) are both harmless and even to be
expected. They certainly should not cause the compiler to demand
duplicate method implementations :)
