hmm, well, probably the result of a halfhearted attempt
to satisfy both, the OpenStep and the MacOS Classic
developers ... but that doesn't belong here ...

just as fact:

# gcc --version

gcc (GCC) 3.3 20030304 (Apple Computer, Inc. build 1666)

# man gcc

file.s
Assembler code. Apple's version of GCC runs the preprocessor on
these files as well as those ending in .S.

file.S
Assembler code which must be preprocessed.

# uname -a
Darwin anson 7.5.0 Darwin Kernel Version 7.5.0: Thu Aug 5 19:26:16 PDT 2004; root:xnu/xnu-517.7.21.obj~3/RELEASE_PPC Power Macintosh powerp

ONTOPIC:

why not move the intermediate files into a separate
subdirectory which can easily be removed on cleanup?

of course, gcc could also be changed to use different
extensions than .s and .S for those files ...

best,
Herbert
