I'm using gdb 5.0 (20001113 Apple version 203 built on 11-07-2001).

After playing around with it for some time I found one problem at least.
gud-gdb-massage-args isn't defined anymore. This function used to append
"-fullname" to the command-line arguments for gdb. With the option
source file locations are given as

/somewhere/in/my/home/directory/file.c

Without the option source file locations are indicated by gdb as

source /somewhere/in/my/home/directory/file.c

And the additional "source " throws gud.el off.

With this fixed

M-x gdb with  gdb ./test               works as expected
M-x gdb with  gdb --annotate=3 ./test  doesn't work ie. no source buffer
                                       but lots of annotations in 
*gud-main*
M-x gdba with gdb --annotate=3 ./test  hangs on first user input in 
*gud-main*
                                                   and no source buffer
                                                   "hang" means nothing 
happens no matter
                                       what I type into *gud-main*

I've looked at gdb-debug-log in the gdba case. Emacs apparently only 
receives
gdb's startup message/version/warranty/copyright and the first prompt. 
Nothing
else is in the log. I'll try to look at it again, but it'll probably take 
me
a while to find the time.
