Fixed definition of instance Enum for tracing.

olaf: Fri Mar 23 19:02:00 CET 2001 Update of /usr/src/master/nhc/src/prelude/Prelude In directory hinken:/tmp/cvs-serv24736 Modified Files: Enum_Char.hs Log Message: Fixed definition of instance Enum for tracing. For tracing the instance lacked definitions for toEnum and fromEnum. The same definitions as for untraced programs can be used. Hopefully not more instance definitions are lacking for tracing; here it really hurts that the compiler, following the Haskell standard, cannot detect missing instance definitions. Unfortunately a missing instance definition leads to faulty byte code for tracing in the current compiler. Still have to modify transformation to give proper runtime error.

Bugfix: hIsEOF gave a strange runtime error.

It seems that passing a newtype'd ForeignObj across the FFI is not identical to passing the ForeignObj itself, as it ought to be.

The previous transformation made pattern bindings strict. Introduced calls of lazySat to make them non-strict. They are now very similar to caf bindings.

malcolm: Thu Mar 22 19:45:29 CET 2001 Update of /usr/src/master/nhc/src/hmake In directory hinken:/tmp/cvs-serv21548 Modified Files: GetDep.hs Log Message: Fix hmake -cpp bug. Hmake was wrongly inserting a -cpp flag on literate source files, because of a % character in the first column. Not sure why the % triggered a need for cpp. Surely only a # is recognised by cpp?

malcolm: Thu Mar 22 19:34:29 CET 2001 Update of /usr/src/master/nhc/src/compiler98 In directory hinken:/tmp/cvs-serv21512 Modified Files: PreImport.hs Log Message: Fix import/hiding/re-export bug + formatting tidy-up. Compiling the following module: module B (x) where import A hiding (x) import qualified A x = ... A.x ... led to an incorrect interface file, where both B.x and A.x were exported.
