cruft in gnat-4.2 upload

[Matthias Klose <doko@cs.tu-berlin.de>]

There's much cruft in the last gnat-4.2 upload, bringing the size of
the diff,gz to nearly 5mb ... instead of 390k for the gcc-4.2
package. You were the one complaining about the big diff's in the
gcc-4.1 source ;-) Plus the b-d on the exact version of gcc-4.2-source
seems to be less than ideal.
