+ * fixed some bugs in the x86-64 port:
+ ** Negative short int return values from c-calls are sign-extended
+ correctly.
+ ** The stack is aligned to 16-bytes for c-calls, as required by
+ the ABI. (thanks to Cheuksan Wang)
+ ** The disassembler understands more x86-64. (thanks to Cheuksan Wang)
+ ** The regression tests use SB-ALIEN:INT instead of SB-ALIEN:INTEGER
+ for enums. (thanks to Vincent Arkesteijn)
