re PR fortran/31189 (Support backtracing for non-library errors)
PR fortran/31189
* runtime/backtrace.c (show_backtrace): Skip _gfortrani_handler
when displaying backtrace.
* runtime/compile_options.c: Include <signal.h>.
(handler): New function.
(set_options): Set signal handlers for backtrace.
* libgfortran.h (handler): Add prototype.
* invoke.texi (-fbacktrace): Document the new behaviour.
