Hello.
I'm looking at adding gcc 4.8 package.
I have a big question about g++-4-runtime package.
For example, OmniOS g++-4-runtime includes
/usr/lib/libstdc++.so.6.0.18
/usr/lib/libstdc++.so.6.0.17
and so on.
we can see that it is linked to libstdc++.so.6. So, if we update link,
runtime linker will load binary incompatible library.
Are there specific incompatibilities between those versions? GCC's C++
ABI has been standardized more than a decade ago, and should be
backward-compatible. While incompatibility bugs have happened, they're
not frequent.

FWIW, I'm maintaining MySQL on OpenCSW, and the libstdc++ library has
been happily upgraded independently from 4.8 to 4.9 without side-effect.
I'm interested to know if there are any that I might have overlooked.
Laurent
