RFD : libg++/gcc/egcs upgrades needed for libc6

[Dale Scheetz <dwarf@polaris.net>]

I just recieved the following from "upstream". It appears that an upgrade
to gcc_2.8.0 and a switch from libg++_2.7.2.8 to libstdc++_2.8 will
resolve some of the problems currently related to libc6.

I would really like to hear back from the maintainers of gcc and libg++ on
the possibilities of making this move. The faster we get there the quicker
packages can recompile their bugs away ;-)

Any other comments or suggestions are, of course, welcome.

Hi Dale,

H.J. Lu send me the following mail. You might discuss with Debian
People to update Debian to egcs 1.0.1/gcc 2.8.0 with libstc++ for
better C++ support.

I'm not using C++ at the moment and can't help therefore - but I might 
consider telling everybody to use egcs 1.0.1/gcc 2.8 for C++.

Cristian, I've cc'ed this since I think this might be of interest for
RedHat also.

Andreas

That is a known problem with libg++2.7.2.8. Basically libg++2.7.2.8
doesn't work very well with glibc 2 due to vtable thunks. It has been
fixed in egcs 1.0.1 and libstdc++ 2.8.0.
