It's more than that.  Setting the flags to -g is a policy decision made
in the mid-90's based on the claim that setting the optimization flag
in any compiler other than gcc would expose bugs in that compiler.

(the claim of course is incorrect, but there's no point in discussing it
on this mailing list)
