2010-06-21glcpp: Initialize error state.Kenneth Graunke
2010-06-21glcpp: Accept #elif without an expression if the expression doesn't matter.Kenneth Graunke
Issue a warning. nVidia's compiler seems to accept this; apparently GCC < 4.4 did as well: http://gcc.gnu.org/gcc-4.4/porting_to.html
2010-06-21glcpp: Rework handling of "defined" operator.Kenneth Graunke
It's now done in the grammar, and as a result, can easily handle parenthesis. defined ( identifier ) is now supported. Fixes glcpp/tests/065-if-defined-parens.c.
2010-06-21glcpp: Ignore junk tokens at end of #ifdef/#ifndef (with warning)Kenneth Graunke
Both nVidia's compiler and GCC accept this. Fixes CorrectPreprocess11.frag.
2010-06-21glcpp: Rename "errors" to "info_log."Kenneth Graunke
Eventually, we'll want to be be able to print out warnings as well.
2010-06-21glcpp: Remove calls to exit().Kenneth Graunke
Calling exit() would be really bad once integrated into mesa. Even in the standalone binary, we want to print the error log first. Since each case already flags an error, compilation will still fail, but it may go on (with something fudged) and generate more errors.

2010-06-21glcpp: Set locations on tokens.Kenneth Graunke
2010-06-21glcpp: Add plumbing to support line locations.Kenneth Graunke
2010-06-21glcpp: Add %error-verbose.Kenneth Graunke
2010-06-21glcpp: Build a reentrant parser.Kenneth Graunke
2010-06-21glcpp: Complain about unrecognized directives.Kenneth Graunke
2010-06-21glcpp: Output to a buffer and error log rather than directly printing.Kenneth Graunke
In the standalone case, simply print the buffers when done.
2010-06-21glcpp: Fix a case of == where = probably ought to be.Kenneth Graunke
Caught by a GCC warning.
