[MLton-commit] r4581
|
From: Matthew F. <fl...@ml...> - 2006-05-24 15:10:32

A somewhat different solution to the issue discussed in r4578. Rather
than include "basis-ffi.h" (and suffer incompatible extern
declarations for Basis Library values imported as _symbol), we
conditionally include either a declaration of WordS<N>_{quot,rem} or a
static inline definition.
Also fixed a bug whereby the inlined Real<N>_Math_* functions did not
have declarations for the underlying <math.h> functions; again, this
is a consequence of "c-chunk.h" not including "platform.h".
Both issues could be solved by including "platform.h" in "c-chunk.h",
but it isn't clear why this was never done before. (Of course, the
extern/_symbol issue remains.)
