### error-check (PRIVATE)
######################################################################
### error-check is a macro target that will peek in the warning and
### error directories to check for the presence of any files.  If they
### exist and are non-empty, then they are assumed to be message files
### and will be outputted then removed.  If they are from the error
### directory, then the target will fail.
