Xmkmf/make problem

[Mike Jeays]

I have several Xlib programs that compiled successfully on earlier
versions of FreeBSD (4.1 and before), using xmkmf and make.  With 5.1, I
get an error message:

"make: don't know how to make /usr/include/machine/ansi.h. Stop"

It looks as though this header file, and several others, have been moved
to other directories.

Is there a simple fix to a configuration file somewhere, or is the
problem fixed in 5.3-BETA?
