	Hmm... That is very interesting, as on my Debian Potato (2.2)
machine, this what gcc is saying:

$ rm ./specs
$ gcc -v 
Reading specs from /usr/lib/gcc-lib/i386-linux/2.95.2/specs
gcc version 2.95.2 20000220 (Debian GNU/Linux)
$ touch specs
$ gcc -v 
Reading specs from ./specs
gcc version 2.95.2 20000220 (Debian GNU/Linux)

Now, if I repeat the experiment on on a Debian Slink (2.1) machine, the
results are different:

$ rm ./specs
$ gcc -v
Reading specs from /usr/lib/gcc-lib/i486-linux/2.7.2.3/specs
gcc version 2.7.2.3
$ touch specs
$ gcc -v
Reading specs from /usr/lib/gcc-lib/i486-linux/2.7.2.3/specs
gcc version 2.7.2.3

I think I have found a bug in the new gcc in Debian Potato! I looked at
the Debian bugs list, and there is not mention of this problem. Looked at
the changelog for the same package, and still no mention of this issue.
Not even anything in the debian-devel mailing list archives. I will post
to the debian-devel and find out what is going on. Thanks for the pointer.
