Re: GNU gcc upgrades

Versions of g++ previous to 3.0 are VERY different from those from 3.0
and up doe to standards compliance.  Basically any moderately
sophisticated c++ code that was written to the original c++
specification would compile with g++ v2.x but the 3.x compiler will
generate mass quantities of errors and exit if fed the same code.
