This will not work in all cases. 

In Gould's UTX/32 (4.3bsd based), some defines are hard-coded in /lib/cpp
(eg. gould, unix etc.) but others are passed on the command line used
by /bin/cc when it calls cpp (eg. -Dselport, -DCOFF).

Other systems may have the same problem. The shell script should
probably be modified to look for '-DXXX' in /bin/cc also.
