I thought this was libgcc_s ?

I've noticed that some programs which do not use the standard c++
library but use exceptions and RTTI used to compile without linking
with libstdc++ in 2.95.x. With 3.0, I have to use libstdc++ to enable
RTTI and exception handling.

So, you're saying that if I'm just using exceptions, RTTI, but no
other stuff, I might be able to link with libsupc++ rather than
libstdc++ ? Something like:

  gcc -o foo foo.cpp -lsupcc++

Is libsupc++ a strict subset of libstdc++ ?

Can I link with both supc++ and stdc++ ? Does it make sense ?
(Methinks no).

So what is libgcc_s for then ?

Thanks,
Phil.
