[RFA] Compile objc-lang.c, objc-exp.tab.c [1/5]

[Adam Fedor <fedor at doc dot com>]

Now that I'm almost done, I finally understand the patch lingo (Thanks 
Michael)! This is a repost of the first of five final patches for ObjC 
suppport:

http://sources.redhat.com/ml/gdb-patches/2003-01/msg00049.html

The other two that I also need approval for are:

http://sources.redhat.com/ml/gdb-patches/2003-01/msg00050.html
http://sources.redhat.com/ml/gdb-patches/2003-01/msg00080.html

and two more (symtab.c, and linespec.c) will be coming soon.

---

A new year brings a final push to get Objective-C support in gdb. This 
patch enables compilation and linking of the Objective-C files. I need 
this now since the remaining patches require so many of the Objective-C 
functions that it would be pointless to submit them otherwise.

2003-01-02  Adam Fedor  <fedor@gnu.org>

	* Makefile.in (COMMON_OBS): Add objc-lang.o
	(YYOBJ): Add objc-exp.tab.o
	(maint.o, utils.o): Add $(objc_lang_h)
	* maint.c (maintenance_demangle): Uncomment language_objc case.
	* utils.c (fprintf_symbol_filtered): Likewise.
	* parser-defs.h (start_msglist, add_msglist, end_msglist): Declare
	Objective-C parsing functions (from objc-lang.c).
