for TypeVar, because the address appears in an
error message

to the main module is imported, and the main module is not an
implementation module.
renamed local function 'scan_dcl_module' into 'scan_main_dcl_module'.

optimize dot dot generators,
fixed bug in array comprehensions with more than one qualifier,
removed 'c' before 'cIsListGenerator' and 'cIsArrayGenerator'

- unused dynamics in where/let clauses do not cause a rule doesn't match
  error in overloading.icl instead they are ignored
- default behaviour changed e.g.

f (i :: Int, j :: Int) = abort "Int"
f (r :: Real, s :: Real) = abort "Real"
f _ = abort "stop"

The compiler first matched on the tuple and then did the dynamic pattern
matches. But the last match did not call the last (default) alternative if it
did not match.
- some small changes

fromString is not yet supported
some error handling improved
parial instances are temporary disabled

ignored the type specification. Now he treats f as a function, and hence
gives a type error

Start = f
  where
    f :: String
    f = 1

changed Declaration type
fixed crash when macro appears only in dcl module
added make with caching in 'main'
use BoxedIdent in hashtable

Tested with compiling Object IO and butstrapping.

- type variables
- passing a list of directly imported dcl modules by an icl modules

- type namen worden gesuffixed met hun definierde module naam

checking of a whole dcl module component --> now cyclic module dependencies
should work

during the transformation phase

moved all switches to syntax module

dcl macros in icl functions and macros
removed expanded macros from groups (s.c.components)

 (changes are commented with "MW0")

of "v314", case defaults and guards now also have file position information.

algorihm so that typing error messages can indicate the alternative in
which the error occured. Before, these error messages always located the
first alternative/function type
