I think -avoid-version is a libtool option rather than a gcc option.
I'm not sure whether it's supposed to be passed down to gcc.

But yeah, gcc 4.6 seems to report the error earlier than 4.5 would. E.g.:

gcc -avoid-version --verbose

doesn't give any error about -avoid-version for 4.5, whereas for 4.6
it does. (Trying to compile something with -avoid-version gives an
error with both compilers.)
