C source code

I just tried to compile the package slang-2.2.4
on gcc-4.8 trunk dated 20120620 on an AMD x86_64 box.

The compiler said

/home/dcb/rpmbuild/BUILD/slang-2.2.4/src/slarith.inc:697:32: internal compiler
error: in expand_shift_1, at expmed.c:2335
  for (n = 0; n < na; n++) b[n] = (2 * a[n]);
