Update lang/gcc42 to the 20061014 snapshot of GCC 4.2.0, which appends a

on the way (enabling Java actually was a noop, except for pkg-plist).
Update lang/gcc41 to the 20061013 snapshot of GCC 4.1.2.
These changes allow us to remove the CONFLICT between lang/gcc41 and
lang/gcc42 when building with Java support (the default on i386).
