[Magic-dev] Illegal overlaps not flagged

Dear Bertrand,

Okay, I found the error, which is that I commented out a line that I
should not have that enables the paint tables that contain the overlap
error rule.

file drc/DRCsubcell.c, lines 572 and following should be:

             savedPaintTable = DBNewPaintTable(DRCPaintTable);
             /* savedPaintPlane = DBNewPaintPlane(DBPaintPlaneMergeOnce); */

             (void) DBCellCopyAllPaint(&scx, &DBAllButSpaceBits, 0, DRCuse);

             (void) DBNewPaintTable(savedPaintTable);
             /* (void) DBNewPaintPlane(savedPaintPlane); */

That is, I meant to comment out the replacement of the paint routine,
but should not have commented out the replacement of the paint table
that is used during DRC subcell flattening.

I am correcting the CVS database, and the new distribution should be
available tomorrow.  Thanks for the bug report.
