Dear all,

please find attached an obvious patch by Steve for a technical
regression that resulted from improvements in error recovery
of bad uses of associate.

Regtested on x86_64-pc-linux-gnu.

Will commit soon unless there are comments.

As a sidenote: the testcase shows that we resolve the associate
names quite often, likely more often than necessary, resulting
in many error messages produced for the same line of code.  In
the present case, each use of the bad name produces two errors,
one where it is used, and one at the associate statement.
That is probably not helpful for the user.

Thanks,
Harald
