I vote for "only with -std=f95" with may be a warning otherwise. I think it is a legitimate optimization to replace A**B by A**I (with I=B) when B is known to be an integer, hence to accept negative values for A in this case. I find upsetting to have to cheat with variables when constant folding does not give the same result as a similar code with variables. -- http://gcc.gnu.org/bugzilla/show_bug.cgi?id=38823
