libgcc/gcc upgrades on 10.5 issues, libgcc versions

[Riccardo Mottola]

Hi!

I am churning updates on all my three 10.5 systems!

I just finished compiling gcc 14 on my PPC today.. even if it is a 2x 
1GHz G4 with 2GB of RAM it took quite a bit. The first attempt froze the 
terminal, so I restarted using xterm and it worked - maybe just by luck.

It also proves that GCC is very slow on PPC, compared to the MacBook 
which is nominally maybe 50% faster, not more

now I have some fallout.. I started opening a bug, but then realized 
that some packages refuse to build allo for the same reason:

be it using gcc-4.2 or gcc14, the issue is in 
/opt/local/lib/libgcc/libstdc++.6.dylib which is a fresh build!

Ideas? On x86 I don't seem to have this issue.

Do we have a specific issue where to track this fallout?
I fear that now compilation of any C++ port is broken!
