I did some looking around on the gcc bugzilla to see if anyone else reported
slow linking or in general problems with g++ when '-g' is used. I found a
GCC bug 25468 (see: http://gcc.gnu.org/bugzilla/show_bug.cgi?id=25468 )
which "might" be related.
I then downloaded the gcc-4.1-source and checked if the PR debug/25468 fix was
included in the source, and it wasn't.
I am not sure if the reported behavior in the GCC bug (25468) and fix would
have any bearing on link times, but I would be happy to try this fix out.
