	gdb            : ChangeLog Makefile.in c-exp.y c-lang.c c-lang.h 
	                 parse.c parser-defs.h 

Log message:
	Expand preprocessor macros in C expressions.
	* c-lang.h: #include "macroexp.h", for macro_lookup_ftype.
	(scan_macro_expansion, scanning_macro_expansion,
	finished_macro_expansion): New function declarations.
	(expression_macro_lookup_func, expression_macro_lookup_baton): New
	variable declarations.
	* parser-defs.h (expression_context_pc): New declaration.
	* parse.c (expression_context_pc): New variable.
	(parse_exp_1): Set expression_context_pc, as well as
	expression_context_block.
	* c-exp.y (yylex): If we're not already reading the result of a
	macro expansion, try to macro-expand the next token.  When we're
	done scanning a macro expansion, switch back to the mainline text.
	Commas and `if's in a macro's expansion don't terminate the input.
	* c-lang.c: #include "macroscope.h" and "gdb_assert.h".
	(macro_original_text, macro_expanded_text,
	expression_macro_lookup_func, expression_macro_lookup_baton): New
	variables.
	(scan_macro_expansion, scanning_macro_expansion,
	finished_macro_expansion, scan_macro_cleanup, null_macro_lookup,
	c_preprocess_and_parse): New functions.
	(c_language_defn, cplus_language_defn, asm_language_defn): Call
	c_preprocess_and_parse, instead of c_parse.
	* Makefile.in (c_lang_h): Note that this #includes macroexp.h.
	(c-lang.o): Note dependency on macroscope.h and gdb_assert.h.
