Stephen Williams a3c1fb8c8a Supoprt precompiled defines
Core preprocessor support for writing out and reading precompiled
defines. The preprocessor can read initial precompiled defines from
any number of specified source files, and can write all the defines
into a specified output file.

Martic Whitaker 577da5c0d3 Fix for assertion error when expanding macro.
The patch for adding support for macros with arguments contained
a leftover debugging aid. This patch corrects the code. It also
should eliminate some compilation warnings.

Martin Whitaker 680196953b Add support for text macros with arguments.
This patch modifies the preprocessor to handle text macros with
arguments. It also fixes a bug that prevented a `line directive
being issued after a multi-line text macro had been instantiated.

Cary R b921a56ad1 A leading underscore is valid for macro substitutions.
For text macro substitutions the lexor did not allow leading underscores.
This patch fixes that omission. All other places that text macros may be
used appear to be correct.

Cary R 3f6ea1d587 Make C style comments work in false/suppressed ifdef/etc. blocks.
C style comments were not recognized as comments in false or
suppressed sections of ifdef/etc. blocks. This prohibited an
unneeded endif/else/etc. from being commented out with this
style of comment.

Cary R d08817aec1 [PATCH] Search for include files relative to the current files path first.

when search for include files.
