Summary : Compatibility standard C++ libraries
The libstdc++ package contains compatibility standard C++ library
from GCC 3.3.4.
In my experience, these are rarely installed, and most users won't know to
install them unless explicitly instructed to do so.
TeX Live maintainer time is a precious resource, so the first priority should
a tl distro that builds and runs on systems tl maintainers use without tricky
hacks that will only cause trouble next eyar. The 2nd should be to ensure that
it builds and runs on other "sufficiently common" systems.
A few years ago, building tl on linux was a big deal. Many users were running
linux on older hardware that was too old for Windows, with small disks and
memory. Compiling a big package could be an adventure. My guess is that
most libstdc++.so.6 linux system can build tl2005 from source with little
This argues for tl binaries targeted for libstdc++.so.5, and a recommendation
that libstdc++.so.6 systems either install the vendor's compatibility libraries
or install the vendor's compilers and development libraries and compile the
