	Syntax.hs TokenId.hs 
Log Message:
Syntactic re-arrangement of FFI calls in the source language.
  * The calling convention is now mandatory.
  * We add `cast' and `noproto' as local calling conventions,
    in addition to the standard ccall, stdcall, cplusplus, dotnet, jvm.
    The latter four are not implemented, but generate an error message.
  * The safety spec now includes `unsafe', `safe', and `threadsafe',
    but these are all ignored in nhc98 for the moment.  (All calls are
    safe, and we don't have threads.)
  * The safety spec now comes before the entity string, not after.
