Hi,
This patch adds missing macros that the dmd front-end makes use of, as
seen on one of the BSDs where the include for int_const.h is guarded,
and defines any __unix__ system as being POSIX.
Bootstrapped and regression tested on x86_64-linux-gnu.
Committed to trunk as r270403.

* d-system.h (POSIX): Define unix as POSIX.
(INT32_MAX, INT32_MIN, INT64_MIN, UINT32_MAX, UINT64_MAX): Provide
fallback definitions.
