UNIX source level debugger

[David Buonomo]

I am in search of alternatives to the dbx source level debugger (we are using
C).  The source level debugger that I've used under VMS, I feel, is quite nice.
Is there anything out there that is similar to this?

I don't know the details of how a variant of UNIX (or more specifically the
C compiler available for that variant) is tied into the debugger, so I don't
know if you can purchase a "UNIX independant" (can be used with Sys V or BSD)
source level debugger.  This is what I would prefer to get.  Please enlighten
me on this subject if you have information to pass along.

Any help would be appreciated and I will post a summary depending on interest.
