********>Bugfix 6
Author: Tom Darden
Date: 2/22/00

Programs: sander

Severity: when order>4 and polarizable potentials are used, the PME
          forces may be inaccurate

Description: a subroutine argument is incorrect in the bspline routines

Fix:  apply the following patch to amber6/src/sander/ew_bspline.f

*** OLD ew_bspline.f        Tue Feb 22 13:51:00 2000
--- NEW ew_bspline.f        Tue Feb 22 13:51:28 2000

Temporary workarounds:  don't run this sort of calculation :-)
