I think clashes should only be a problem if you are using different
versions of this macro in different directories. If so, that's a
no-no. It has always been the case that all configure scripts in a
given project must agree about how to compute cache values. I think
this is an undocumented requirement :-(, but careful examination of
the ChangeLogs will show bug fixes for problems like this dating back
at least to 1996.
HTH,
