another example of bug reported yesterday (?)

[Paul E Condon <pecondon at quiknet dot com>]

While attempthing a build of kernel-2.4.12, I typed "make modules" and 
got an error. The rerun of the offending compile step resulted in this:

This looks like it might be another example of the same bug that I 
reported yesterday, but on different source code. Maybe a second example 
will help squash the bug faster.

Cheers and thanks for gcc.
