Thank you for your report.

I've just compared the header files you mentioned above in Emacs 20.6
and Emacs 21.1, and found out that only s/usg5-3.h was changed.
However, "#define COFF" was not one of the changes, it was there in
Emacs 20.6 as well.

Could you please look into the 20.6 source directory where you built
Emacs on that system, and post here what system configuration did the
configure script pick up, and what header files in src/m and src/s
did it include?  Perhaps your system was treated as a different one
back there?
