[gradsusr] undef in GrADS 2

[Phil Cogbill]

Works like a charm!  I had seen this note, but thought that since we had
a newer version of GrADS than 2.0.a6 that it wouldn't be an issue.  Like
a version specific bug since it says...

"  If you are administering a GDS version 2.0 with GrADS 2.0.a6 behind
it...  "

 This is a huge help and has cleared up a lot of issues we had coming
from GDS.  Thanks a TON!

Again, thank you so much!
