For current systems we have earlier this year switched to DWARF, but we
will need to support STABS for legacy systems for a few years.
As far as it being obsolete, I asked about its status in January 2013 on
the gdb list. My take away from that discussion was that it was not
deprecated nor obsolete and that it was being maintained; but, that new
development was focused on DWARF.
[As far as DWARF goes, we use DWARF 3+/4 and GCC 4.7+ as we use -g3 to
get macro debug information and want the strings to be consolidated.]
