Watch expressions only work for GDB 6.0 onwards, so you might try updating.
Emacs normally tells you this but, in this case, the mode failing before then.

All the annotations appear to be present. You could check for the post-prompt
annotation:

b main

^Z^Zpost-prompt

^Z^Zbreakpoints-invalid
Breakpoint 1 at 0x804843f: file myprog.c, line 38.

^Z^Zpre-prompt
(gdb) 
^Z^Zprompt

I think that they must be present, though. It's hard to know what's wrong but
here are a few ideas:

Perhaps other Mac OS X users could e-mail this list to say whether they
experience the same problem or not.

A .gdbinit file in your executable's or home directory may be affecting things
(try gdb -nx).

Try "gdb -noasync -ann=3 a.out". I think I've seen the output order get jumbled
with "-aysnc" (the default). Watch expressions don't to work with this
option, though, as they use GDB's new interface GDB/MI.

I have recently created a file called gdbmi.el that uses this new interface
which GDB developers intend to replace annotations. You can download it from
http://nick.uklinux.net. It needs the CVS version of gdb which should be
released as GDB 6.1 around the end of March. GDB/MI should be more robust than
annotations so I would be interested to know if you can get this file to work
on Mac OS X.
