Patching gdb 5.0 for XFree86 module support

I've been working the last few days on porting an older gdb
4.18 patch that adds support to gdb for debugging XFree86
loadable modules in place without requiring a static server
build. This has several advantages for an XFree86 developer, as
well as for the more technical user out there who is capable of
debugging a problem, but not necessarily willing or capable to
rebuild XFree86 from source as a static server.
My goal is to get this patch sync'd with current gdb that will
ship with the next version of Red Hat Linux, and provide it on
ftp://people.redhat.com/mharris and elsewhere for people to snag
a copy.
When I started this the other day, I had never looked at gdb
source before, so bear with me. ;o)
I first ported the patch to at least apply cleanly to current
source, making some guesses along the way when not 100% sure what
was correct. I've fixed all compilation warnings and all
compilation errors but one now, which I'm not yet sure how to
resolve as I'm not too familiar with gdb internals.
gcc -c -O2 -march=i386 -mcpu=i686 -DXFREE_MODULE_SUPPORT -I.

For those willing to help, or offer advice, I've put my SRPM at:
ftp://people.redhat.com/mharris/hacks/gdb-5.0rh-15.4xfree.src.rpm
The patch is also attached to this message as well, and contains
further comments on my progress, etc.
I'd be greatful for any suggestions anyone may have that help get
this working. Also, what is the best list for such discussion?
Thanks in advance for any help.
