[dmd-internals] dmd commit, revision 569

[Walter Bright]

It is rather trivial. The main annoying problems were the change from 
unsigned long => 64 bits wide, and the size/alignment of long doubles 
changed. The former means there is no longer a 32 bit integer type 
portable from 16=>32=>64. Bleh, although I don't foresee ever rebuilding 
the compiler as a 16 bit host.
