Package: gcc
Version: 2:2.95.4-6
Severity: wishlist

As in subject: I think that cc and gcc should be provided
through update-alternatives mechanism, so user could
switch between gcc272, gcc-2.95 and gcc-3.0 more easily.

Eg. use gcc-3.0 for cc but gcc-2.95 for gcc or whatever...

fine with me. for the record here the explanation:

gcc-x.y doesn't use alternatives to make sure that the preferred
system compiler is used when calling 'gcc'. switching the compiler
may break your system (will break for C++). In most gcc-x.y versions
ABI's are different.

If you want to test gcc-x.y for a particular package,

- use CC=gcc-x.y CXX=g++-x.y when configuring/compiling a package

- make ~<user>/bin/gcc a symlink to gcc-x.y and add it to your path

- if you know what you do, there is the option to divert the gcc/g++
  links.

closing the reports, adding to our karma.
