[AD] Getting Allegro to build with BCC32

["Owen Rudge" <owen@xxxxxxxxxx>]

Hi,

I spent some time tonight trying to make Allegro build with BCC32. I had
partial success. I made a few modifications to some of the source files in
src/win - the attached patch contains these (tested with BCC32 5.5 and
MingW32). I also had to add:

#define _getdrive()   getdisk()

to include/allegro/platform/albcc32.h (and uncomment the "Currently BCC32
cannot build the library" bit, obviously).

I've discovered that you have to build wddaccel.c, wddmode.c, wddovl.c,
wddlock.c, wddwin.c and wwnd.c as C++ files, mainly due to DirectX headers
and Borland C++ not liking various things in them (eg, unions). Really, the
only problem after this is assembly code, by the look of it. Here are the
linker results:

Any ideas what can be done about this?
