[cvs-nhc98] Create library src/prelude/Hat for portable Hat.

olaf: Mon Oct 15 18:37:14 CEST 2001 Update of /usr/src/master/nhc/src/prelude In directory hinken:/tmp/cvs-serv3596/prelude Modified Files: Makefile Log Message: Create library src/prelude/Hat for portable Hat. Hat.hs contains all the combinators used in transformed code and initialisiation etc for tracing. Hat.c/h contains the C-implementations. MagicTypes.hi is a hack to enable C-types to live in nhc's heap. Note that the current version still depends in several ways on nhc, but the library should work with a normally compiled transformed Haskell program. The library has not been tested yet. Code is mostly copied (and modified) from PreludeDebug, HatArchive and trace/runtime. include/hat.h was renamed to include/art.h
