The -gstabs option supplied to gcc 3.2.1 works for me.  I'm happy now.
Here is blurb from the gdb info page:

     _Warning:_ GDB can only debug C++ code if you use the proper
     compiler.  Typically, C++ debugging depends on the use of
     additional debugging information in the symbol table, and thus
     requires special support.  In particular, if your compiler
     generates a.out, MIPS ECOFF, RS/6000 XCOFF, or ELF with stabs
     extensions to the symbol table, these facilities are all
     available.  (With GNU CC, you can use the `-gstabs' option to
     request stabs debugging extensions explicitly.)  Where the object
     code format is standard COFF or DWARF in ELF, on the other hand,
     most of the C++ support in GDB does _not_ work.

Thank you for your help.
