Re: Add rules for ObjC files

[Klee Dienes <klee at mit dot edu>]

I'm not sure if this is something you want to hassle with at the  
moment, or if you'd prefer to let it wait as a modification once a  
working version of the Objective-C patches are successfully committed.

But just as a heads-up, I should mention that in more recent versions  
of our GDB, we've folded in all of the Objective-C support directly  
into c-exp.y, and removed objc-exp.y as a file entirely.  Most of  
objc-exp.y was always just an out-of-date copy of c-exp.y, anyway;  
moving the (rather small) changes into c-exp.y directly not only  
allowed us to track changes to the C parser much more smoothly, it  
should also allow for much better Objective-C++ support.

You'll probably want to look at the most recent version of our GDB tree  
(http://www.opensource.apple.com/projects/darwin/6.0/source/other/gdb- 
20020918.tar.gz; no registration or anything similar required), and  
check out our changes to c-exp.y; I've attached them for your  
convenience.

One downside to having the changes directly in c-exp.y is that I don't 
know of any good way to conditionalize them; though I am by no means a 
bison guru.

The following diffs are unrelated to Objective-C; I'm attaching them 
just for your reference (the ones in generic.diffs are likely to be 
removed in our sources soon as well; the ones in number-parsing.diffs 
remove a memory leak caused by calling parse_number on invalid, but are 
unrelated to the Objective-C changes).
