Ummm, just to be clear, you're not about to make the test results worse
with gcc 2.95.3, are you?
BTW, gcc 2.95.3 on native i686-pc-linux-gnu does indeed default to
stabs+, but who knows what the default is on various distros. And here
is a quick list of some gcc-2 based distros: freebsd 4, netbsd 1.6,
openbsd 3.4, debian 3.0, vine 2.6, gnoppix 0.6, lindows 4.5,
lycoris build3.
My personal estimate/opinion is that gdb HEAD can drop support for gcc 2
some time around October 2005.
