I didn't think my memory was getting that bad..... Then what is the solution? It would not feel right to require programs that are asking for "libposix" to also call a non-posix function just because it is convenient for the error POSIX module. If it is only OS X, then I would think that this would work: char * program_name; #ifdef OSX //whatever #pragma weak program_invocation_name // program_name not being program_name. #endif requiring a call to set_program_name just seems so wrong for a posix lib.
