When libgfortran/intrinsics/signal.c is built at -m64, a number of warnings
occur...

*status = (int) signal (*number, (void (*)(int)) *handler);
signal (*number, (void (*)(int)) *handler);
from the subroutine...
void
signal_sub (int *number, void (*handler)(int), int *status)
...for the first warning and from the subroutine...
void
signal_sub_int (int *number, int *handler, int *status)
Note: Thomas Koenig comments that since signal() returns a pointer to the
previous signal handle and
g77 uses an integer variable wide enough to hold the STATUS argument, we should
do the same.
