Also I'd prefer doing this without #ifdef;

        if (defined(NO_FAST_WORKING_DIRECTORY) &&
        	!want_file && has_sha1_pack(sha1, NULL))
		return 0;

Are you sure? AFAIU it is an OS dependent problem, so it should not be 
configurable at runtime anyway.

Well, defined(SYMBOL) does not seem to be a valid C X-<, and I
rewrote it in what I committed.  But the point was that the
whole thing:

	if (!FAST_WORKING_DIRECTORY && whatever)
		statement;

when FAST_WORKING_DIRECTORY is a compilation time constant,
would be optimized out for sane platforms with a reasonable
compiler.
