* diagnostic.c (trim_filename, fancy_abort): Moved here from rtl.c. (fatal_function, set_fatal_function): Removed. (fatal): Don't prepare for or call the fatal_function. (diagnostic_lock, error_recursion): New. (diagnostic_for_decl, report_diagnostic): Guard against re-entering the error reporting routines. (fancy_abort): Assume function is not NULL. * errors.c (fancy_abort): New. Assume function is not NULL. * tradcpp.c (fancy_abort): Assume function is not NULL. * system.h: Provide default definition of __FUNCTION__. * rtl.h: Use __FUNCTION__ not __PRETTY_FUNCTION__ throughout. Always use __FUNCTION__ in definition of abort. * tree.h: Likewise. * varray.h: Likewise. * toplev.h: Likewise. Don't prototype set_fatal_function. From-SVN: r35170
