- egcs-1.2 is gcc-2.95.
- egcs-1.1.x is based on on a code branch from August 1998.
- gcc-2.95 includes gcc-2.8.1 and all changes made up to September
1998.
- inclusion off all missing gcc-2.8.x code is planned for 2.96 (or
3.0, don't know exactly).

gcc-2.95 uses new library version numbers for libstdc++
(2.10). valarray support is added in this version.
You can test the gcc-2.95 packages in the project/experimental
distribution. gcc-2.95 will be uploaded as sonn as possible; the code
is almost frozen.
- g++ is more conformant (and more restrictive) to the standard.
- much better support for alpha (and powerpc?). Compiles now packages
that could'nt compiled before.
- More aggressive optimization (however kernel must be compiled with
-fno-strict-aliases).
