OK. So I go looking at what has been included, and I find:
% egrep /usr/src /usr/obj/gerbils/2.2/src/tmp/usr/include/machine/asmacros.h
#include "/usr/src/lib/libc/i386/DEFS.h" /* XXX blech */
%
Is there any reason why this is the case? Since this file is used
only by msun (per the comments) in the non kernel case, can't this be
done better?
Are there other gotcha's that I'm setting myself up for by not having
my sources in /usr/src?
