Highly annoying packaging change from 2.8 -> 2.9

[Greg Hudson]

I'd just like to alert you guys to an unpleasant problem which
occurred in the change from gcc 2.8 to gcc 2.9.  I'm not sure if
there's much you can do about it at this point, except try not to
repeat the problem in the future.

In gcc 2.8.1, there is a file at the top level named INSTALL.  In
2.9.2, there is a directory at the top level named INSTALL containing
a single file "README".  For those of us who import gcc sources into a
CVS repository, this is totally unworkable; CVS does not allow a
directory and a file to exist in the same place at the hierarchy.  So
anyone who imported gcc 2.8.1 cannot import gcc 2.9.2 and have a clean
copy.

Compounding matters, I don't think there was any good reason for
INSTALL to become a directory.
