H. Peter Anvin 8b26247442 preproc: add %i... variants, evaluated macro parameters, cleanups 
All directives which create single-line macros now have %i... variants
to define case-insensitive versions. Case insensitive rather sucks,
but at least this way it is consistent.

Single-line macro parameters can now be evaluated as a number, as done
by %assign. To do so, declare a parameter starting with =, for
example:

%define foo(x,=y) mov [x],macro_array_y

... would evaluate y as a number but leave x as a string.

NOTE: it would arguably be better to have this as a per-instance
basis, but it is easily handled by having a secondary macro called
with the same argument twice.

Finally, add a more consistent method for defining "magic" macros,
which need to be evaluated at runtime. For now, it is only used by the
special macros __FILE__, __LINE__, __BITS__, __PTR__, and __PASS__.

__PTR__ is a new macro which evaluates to word, dword or qword
matching the value of __BITS__.

The magic macro framework, however, provides a natural hook for a
future plug-in infrastructure to hook into a scripting language.

              NASM, the Netwide Assembler.

Many many developers all over the net respect NASM for what it is
- a widespread (thus netwide), portable (thus netwide!), very
flexible and mature assembler tool with support for many output
formats (thus netwide!!).

Now we have good news for you: NASM is licensed under the "simplified"
(2-clause) BSD license.  This means its development is open to even
wider society of programmers wishing to improve their lovely
assembler.

The NASM project is now situated at SourceForge.net, the most
popular Open Source development site on the Internet.
