Now that you mention it, I was compiling the kernel when the last exception
happened.. The rest fit into this pattern too. I took a closer look, and the
exception occurs during the following:

ar rcs cdrom.a

This creates an 8 byte file with '!<arch>' in it. I'm using binutils,
gcc 2.7.2 and the exceptions began with either kernel 2.1.23 or 24, and are
still here in 25. None of the files in the directory ar is run in are compiled
during 'make', but cdrom.o is compiled as a module. Something is awry..
