It is precisely because the identification varies with the way to file name is passed to the compiler that makes setting __FILE__ desirable. The compiler invocation details are not always under the developer's control. Tools like 'make', 'autoconf' and 'automake' dictate the forms. So, I have fairly strong objections to calling it an external procedural BUG. The issue REALLY is that __LINE__ gets messed up; leave discussions of how the compiler is invoked out of it.
