ross 2002/10/27 17:32:40 PST Modified files: src/unix configure.in configure . Install Log: Uncomment the --enable-double-precision option to configure, but leave it off by default. It's also ignored if sizeof(double) > 2*sizeof(int), because Hugs stores a double as a pair of cells.

Does this mean that we can safely enable USE_DOUBLE_PRECISION now? If so, I think we should do it for this release. Obviously the best thing would be Float = float, Double = double, but I think most people would prefer Float = Double = double to Float = Double = float.

(At > least, that's what I've been doing.) Alastair, can I check a couple of things with you: I've changed configure in CVS so that the FFI is enabled by default if one of the header files for dynamic loading is found (the same test you use in machdep.c for defining getDLL() and friends). I'm assuming that that means static imports should be available, though dynamic ones may not be. Is that right? Levent (and Oliver Braun) asked why ffi-using modules are compiled in the install directories (rather than in the build tree and merely copied on install, like everything else). Is that because the alternative doesn't work if your build tree is full of symbolic links, due to path canonicalization?

erkok 2002/10/24 23:34:06 PDT Modified files: src static.c Log: make sure implicit-parameters are not allowed in let-generators of the mdo-notation too (just like those of the do-notation). otherwise, we were getting the amusing error message: Control.Monad.Fix> mdo {let {?x = 2};print ?x} ERROR - Type error in application *** Expression : ( $0 *** Term : ( *** Type : () *** Does not match : a -> b now we get: Control.Monad.Fix> mdo {let {?x = 2};print ?x} ERROR - Currently illegal to bind implicit parameters in the recursive do-notation Jeff: I guess this also shows that just "not-checking" for the existence of implicit parameters is not sufficient to have them supported everywhere.. (plain old "do" also has similar problems.) Revision Changes Path 1.114 +10 -3 hugs98/src/static.c

ross 2002/10/24 17:31:25 PDT Modified files: libraries/Hugs Prelude.hs Log: More H98-compliant Enum instances for Float, Double and Ratio, by adding succ and pred, and copying fromEnum from the Report (so it gives a runtime error for out-of-range values). Ratio still doesn't have H98's quirky termination condition. Revision Changes Path 1.9 +9 -3 hugs98/libraries/Hugs/Prelude.hs
