The runtime loader now reads a part of the .comment section of each

shared object to find out the GCC version it has been compiled with.
This is not an exact science, since we've got the version string for
every single object file that has been linked in, but my heuristic seems
to be good enough.

Having the gcc version at hand will allow for two features: Enabling
work-arounds for old executables (like the type info problem in BeOS
apps), and automatically selecting the right set of libraries in a mixed
gcc 2/gcc 4 environment.
