Surprise, all Unixes are not alike.

It just so happens that I have a Bull DPX/2 with manuals at my
disposal, and they confirm what Mr. Preen says. I can not
determine a way to cause cc to rename the .o file.

On other Unixes I have used (BSD, Sun, Xinu), -o does in fact
specify the name of the output file regardless of the particular
compilation step being performed.

OS-dependent compiler flags are one of life's little joys
for me as a programmer attempting to build software on an
array of different platforms. I will abstain from comment
on what the "correct" cc argument syntax/semantics should
be.
