That worked. Even I didn't realize those as macros. But now I land in
new error.

So I went and put #undef isnan again before #include "fdlibm.h" in
s_isnan.c and now I stop at a new error, again not mentioned in your
reported issue.

I guess this is because of commenting out 9obj.c from compilation. So I
modified 9obj.c, below is the patch
vasudev@rudra:~/Documents/C_programming/compilers/9-cc$ hg diff
src/libmach/obj.c

That took compilation further but now it breaks at point 4 in your
issue. I hope I won't encounter more new issues :-).
Cheers,
