bda7a6e371 ctype.h: wrapper ctype functions with a cast to (unsigned char)
ctype functions take an *int*, which the user is expected to have
taken the input character from getc() and friends, or taken a
character and cast it to (unsigned char).

We don't care about EOF (-1), so use macros that cast to (unsigned
char) for us.

cfb7176ca2 Move the output format macros into the macros.pl mechanism
Move the handling of "extra" macros (i.e. output format macros) into
the macros.pl mechanism.  This allows us to change the format of the
internal macro store in the future - e.g. to a single byte store
without redundant pointers.

Also, stop using indicies into a long array when there is no good
reason to not just use different arrays.

fcb8909749 Move all the RAA code out of nasmlib
The RAA code doesn't have to be in nasmlib; it is only used by nasm
itself, and is better handled in a separate module.

1803dedae8 Move all the SAA code out of nasmlib
Move all the SAA code out of nasmlib; it's not used by anything than
nasm itself.  Cleaning out the kitchen sink known as nasmlib is a good
thing, too.

c735d1a6b2 Replace the WSAA macros with functions
Change the WSAA macros into functions; reducing the icache footprint.

cb38f505e4 WSAA: make the WSAA macros contain their own buffer
Make the WSAA macros contain their own buffer definitions.  This
eliminates the need to have a separate "workbuf" declared in the
outelf backends, which isn't even used for anything else, except for a
few completely redundant strcpys.

Note: these macros probably should be replaced with actual
functions.  The overhead of the function call is likely to be more
than offset by lower icache footprint.

2d900f5488 Avoid obscure segfault in DWARF generation
If DWARF debugging info is requested, and no section
is marked executable, output empty debug sections,
instead of allowing assembler to segfault.

72ec0e4144 Temporaries in macros need a unique prefix; WSAA*() macros to header
When using temporaries in macros, given them a unique prefix to avoid
namespace collisions when using one macro inside another.

Move the WSAA*() macros from outelf32/outelf64 to a separate header
file.

338a3b6882 Clear up WRITE macros causing compile failures with Watcom
The OpenWatcom compiler warns about invalid shifts (correctly, it
appears) due to the non-X86_MEMORY versions of the various WRITE
macros.  Fix.

4095197f6c Cast 64-bit switch expressions to (int) to keep OpenWatcom happy
Our size arguments are 64-bit values, but we don't need that range for
anywhere where we need a switch.  OpenWatcom can't deal with them
(sigh), so cast them to (int) for now.

d1fb15c154 Address data is int64_t; simplify writing an address object
Address data is always int64_t even if the size itself is smaller;
this was broken on bigendian hosts (still need testing!)

Create simple "write sized object" macros.

34f6fb0a65 Don't combine type and size into a single argument
Don't combine type and size into a single argument; *every* backend
immediately breaks them apart, so it's really just a huge waste of
effort.  Additionally, it avoids using short immediates in the
resulting code, which is a bad thing.

70055964fc Additional uses of bool and enum
Proper use of bool and enum makes code easier to debug.  Do more of
it.  In particular, we really should stomp out any residual uses of
magic constants that aren't enums or, in some cases, even #defines.

6867acc18e Use the compiler-provided booleans if available, otherwise emulate
Both C and C++ have "bool", "true" and "false" in lower case; C
requires <stdbool.h> for this, in C++ it is an inherent type built
into the compiler.  Use those instead of the old macros; emulate with
a simple typedef enum if unavailable.

fe501957c0 Portability fixes
Concentrate compiler dependencies to compiler.h; make sure compiler.h
is included first in every .c file (since some prototypes may depend
on the presence of feature request macros.)

Actually use the conditional inclusion of various functions (totally
broken in previous releases.)

21d6be423f Minor fixes needed to compile with MSVC++ 2005
Minor fixes to make it possible to compile with MS Visual C++ 2005.
Unfortunately, MSVC++ is not fully C99 compliant; in particular, it
doesn't handle interspersed declarations and other code.  Furthermore,
it chokes on some expressions in outelf64.c, which fortunately can be
easily substituted with simpler expressions.

Finish the perfect hash tokenizer, and actually enable it.

Move stdscan() et al to a separate file, since it's not needed in any
