breaking C++ by line numbers

[Scott Johnston]

Using the latest versions of gdb (9/10/01, from both the 5.0 and 5.1 branch, 
compiled on i686-pc-linux-gnu), there is a consistent problem setting break 
points by line number in any
C++ module compiled with gcc-3.0 or gcc-3.0.1, i.e.:

(gdb) break main.c:263
No line 263 in file "/home/scott/src/ivtools-0.9/src/drawtool/LINUX/../main.c".

Apologies if this is redundant bug post.  Is there a way to browse the entire 
GNATS database without resorting to keyword guesswork?  This is not obvious 
from the
http://sources.redhat.com/gdb/ entry point.
