5383e28ea0 change string([]byte) to pass array, rather than &a[0], 
to string convert.  if the byte array has length 0,
the computation of &a[0] throws an index bounds error.

for fixed size arrays, this ends up invoking arrays2d
unnecessarily, but it works.

This makes it easy to build with other flags
(like -ggdb) or other compilers (like cc64).

9aad9fef76 make 6a, 6c, 6g, 6l, libmach_amd64 build on 64-bit gcc. 
these guys really really want long to be 32-bits,
so ,s/long/int32/ (and then manual fixup).
still passes all tests.

(i started out looking for just those longs that
needed to be int32 instead, and it was just too hard
to track them down one by one.)

the longs were rare enough that i don't think
it will cause integration problems.

from the first. thus
