� g| _ d| _ dS )a Create a new CParser.
Some arguments for controlling the debug/optimization
level of the parser are provided. The defaults are
tuned for release/performance mode.
The simple rules for using them are:
*) When tweaking CParser/CLexer, set these to False
*) When releasing a stable parser, set to True
lex_optimize:
Set to False when you're modifying the lexer.
Otherwise, changes in the lexer won't be used, if
some lextab.py file exists.
When releasing with a stable lexer, set to True
to save the re-generation of the lexer table on
each run.
lexer:
Set this parameter to define the lexer to use if
you're not using the default CLexer.
lextab:
Points to the lex table that's used for optimized
mode. Only if you're modifying the lexer and want
some tests to avoid re-generating the table, make
this point to a local lex table file (that's been
earlier generated with lex_optimize=True)
yacc_optimize:
Set to False when you're modifying the parser.
Otherwise, changes in the parser won't be used, if
some parsetab.py file exists.
When releasing with a stable parser, set to True
to save the re-generation of the parser table on
each run.
yacctab:
Points to the yacc table that's used for optimized
mode. Only if you're modifying the parser, make
this point to a local yacc table file
yacc_debug:
Generate a parser.out file that explains how yacc
built the parsing table from the grammar.
taboutputdir:
Set this parameter to control the location of generated
lextab and yacctab files.

with the entries:
* qual: a list of type qualifiers
* storage: a list of storage type qualifiers
* type: a list of type specifiers
* function: a list of function specifiers
This method is given a declaration specifier, and a
new specifier of a given kind.
If `append` is True, the new specifier is added to the end of
the specifiers list, otherwise it's added at the beginning.
Returns the declaration specifier, with the new
specifier incorporated.
