DMD include bug

[Doug Gwyn <gwyn>]

DMD release 1.1 <jerqproc.h> has a conflict with <sa.h> in
stand-alone (-J) mode, in that <sa.h> #defines "cursor"
which is also the name of a member of a <jerqproc.h> structure.

A temporary workaround in <jerqproc.h> is:

...
#undef cursor	/* DAG -- workaround for <sa.h> conflict */
	Texture16 * cursor;
...
