some header sources not seen from gdb

[Dave Lawrence <dgl at integrinautics dot com>]

When compiling with gcc 3.2.1 and 3.2.2, I no longer
can see header files among my sources from gdb.  When
I do "info sources", I don't see my header files.
Also, when I try "list hello.h:1", gdb says it can't
find my header file.  In gcc 2.96, I was able to
see my headers from gdb.  How can I get the old
results using gcc 3.*?  Below is an example of
what I'm talking about.  Thanks in advance!

By the way, I originally thought this was a
gcc issue, not a gdb issue, but I posted to
the gcc-help mailing list and received no
responses then submitted a gcc bug report
to redhat bugzilla and had it re-assigned
to the gdb module.  The person who reassigned
it had the following comments:

hello.h appears to be both in .debug_line file table:
     readelf -wl hello | grep 'hello\.'
       1     0       0       0       hello.c
       2     0       0       0       hello.h
     and hellomsg is said to be on line 1 in hello.h:
     readelf -wi hello | grep -C3 hellomsg
