[Bug libfortran/24927] New: libfortran isn't parallel build safe

[hjl at lucon dot org]

Makefile in libgfortran has

selected_int_kind.lo: intrinsics/selected_int_kind.f90
        $(LIBTOOL) --mode=compile $(FC) $(AM_FCFLAGS) $(FCFLAGS) -c -o
selected_int_kind.lo `test -f 'intrinsics/selected_int_kind.f90' || echo
'$(srcdir)/'`intrinsics/selected_int_kind.f90

But it doesn't depend on selected_int_kind.inc. With "make -j 4", I got

/export/build/gnu/gcc/build-ia64-linux/./gcc/gfortran
-B/export/build/gnu/gcc/build-ia64-linux/./gcc

selected_real_kind.lo has the same problem and I suspect there are more than
those 2.
