I'd rather use the same scheme as everyone else. Why be incompatible when you don't have to?

I think GCC can be changed to use the same scheme for dwarf2 as everyone else. This (untested) 
addition to gcc's djgpp.h should do the trick:

#undef DBX_REGISTER_NUMBER
#define DBX_REGISTER_NUMBER(n) \
  ((write_symbols == DWARF2_DEBUG) ? svr4_dbx_register_map[n] : dbx_register_map[n])
