Fix 2005/giljade to work with 64 and 32-bit

The problem was due to sizes so the long * is now an int *. I have no
idea what made me think of it other than on a hunch (and based on my
previous suspicions).

Format fix README.md as well.

Update bugs.md. Added an INABIAF as well as change the status of the
program not working on some platforms to a known bug. This is to due
with clang's deficiency in not allowing the args of main() to be
different. Believe it or not some of the problem appears to be more than
two spaces in the program (other than where it originally was).

Added alt code - the original that will not compile with clang but with
the 64-bit fix. This is because the fix for clang breaks the self-test
feature of the program. Maybe the clang fix should be the alt code. I
don't know.

Updated .gitignore.

Of course the above fix to the code and the adding of the alt code means
that the Makefile was also updated.
