Sorry, I am really busy, and didn't participate in this thread, but
NO! dwarf1 support should be dead. I am looking at gcc:

% grep DWARF config/*
these are the only references to DWARF1 I can spot, and I bet are really old.

config/elfos.h:/* System V Release 4 uses DWARF debugging info. */
config/elfos.h:#define DWARF_DEBUGGING_INFO 1
config/ptx4.h:/* Use DWARF debugging info by default. */
config/ptx4.h:#define PREFERRED_DEBUGGING_TYPE DWARF_DEBUG
