Bug#635370: Bug #635370: busybox: integer overflow in expression on big endian
For the fun out of it all. The original code, even if
gcc produced a warning, worked correctly. Several attempts
to silence this warning produced worse or incorrect _code_.
I'm reverting the "fix" and marking this bug as not fixed.
The issue here is that enums in C are signed. So once you
set the most significant bit to 1 the result gets promoted
to larger size (64bit in this case). So further arith with
this constant were done in 64bits instead of 32bits.
