re PR fortran/30947 (intrinsic: ALARM)
PR fortran/30947
* iresolve.c (gfc_resolve_alarm_sub): Suffix the subroutine name
with the kind of the STATUS argument.
* intrinsics/signal.c: Create specific versions of alarm_sub and
alarm_sub_int according to the integer kind of the last argument.
* gfortran.map (GFORTRAN_1.0): Remove _gfortran_alarm_sub and
_gfortran_alarm_sub_int, add _gfortran_alarm_sub_i4,
_gfortran_alarm_sub_i8, _gfortran_alarm_sub_int_i4 and
_gfortran_alarm_sub_int_i8.
