+ Your gcc has not been compiled for the exact release of
+ your operating system ($gccosandvers versus $osname$osvers).
+
+ In general it is a good idea to keep gcc synchronized with
+ the operating system because otherwise serious problems
+ may ensue when trying to compile software, like Perl.
+
+ I'm trying to be optimistic here, though, and will continue.
+ If later during the configuration and build icky compilation
+ problems appear (headerfile conflicts being the most common
+ manifestation), I suggest reinstalling the gcc to match
