Comment (by rhaas):

 Just removing them violates our policies for removing features. However
 testing this just now it seems that (using the Piraha parser) global
 parameters are currently broken so we can be relatively sure that no one
 was using them (they seem to work if I turn off piraha with piraha_active
 = 0 in ParseFile.c).

 So, given that we de facto no longer support global parameters, we should
 remove them from the documentation and I am fine with changing the error
 message either as comment.2 or comment.3 indicate. I think that error
 messages should use CCTK_VWarn(1,...) rather than std::cout though so that
 they appear in the error stream and that registered callbacks can catch
 them.
