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

[Adam Fedor <fedor@doc.com>]

[-- Attachment #1: Type: text/plain, Size: 744 bytes --]

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.
