The presence of "-fno-common" in C_SWITCH_SYSTEM in darwin.h prevents
linking against a static ncurses cause the symbols UP, BC and PC will be
defined also in the __DATA segment of terminfo.o; why is it needed?

It is needed on other systems.
Why do you link with -fno-common, anyway? Can you do without it?

The question is if it is needed on darwin; the only other arch that uses
it is alpha.

I am not doing anything; look at line 266 in src/s/darwin.h; configure
sets CPPFLAGS to the value of C_SWITCH_SYSTEM, which includes -fno-common.

I've never made changes to this part either (why did you directly send
me the original post?) Anyway, it compiled without -fno-common even
on Mac OS X 10.1.5 (with gcc 3.1).

Thanks for the info. Does that mean we can remove -fno-common from
darwin.h, or do I miss something?

Probably it can be removed, but not 100% sure because I'm not familiar
with this. I'll remove it if there's no objection for a few days, or
there's a statement that it can definitely be removed.

I don't know. If you can build Emacs without it, the answer is
probably no.

Sorry, I'm not familiar with the Darwin configuration. Someone who is
should tell why -fno-common is required on that platform.
