(j3.2006) C12101 and C12102

[Van Snyder]

C12101 says a pure subprogram shall not contain a <stop-stmt>

C12102 says a pure subprogram shall not contain an image control
statement.

Subclause 8.5 says a STOP statement is an image control statement.

Do we need to keep C12101?

There is no constraint against an ERROR STOP statement.  Is that
intentional or an oversight?

Was an ERROR STOP statement intended to be listed as an image control
statement?  (I hope not!)
