Hi,
see [patch 1/5], particularly:
(3) Currently there is no backward or forward compatibility although there
could be one implemented. Personally I think the 'compile' feature is
still in experimental stage so that it is OK to require last releases.
At least in Fedora we can keep GDB<->GCC in sync.
GDB counterpart:
[PATCH 2/4] compile: Use libcc1.so.0->libcc1.so.1
