+ added support for passing optional parameters to called function, f.e.:
proc p( a, b, ... )
qout( a, b, "X", ... )
* forbid creating function pointer when function is used with parameters,
f.e.: x:=@f1(1,2,3)
* harbour/source/compiler/complex.c
* cleaned all restrictions on reserved words I've found - if I missed
sth then please inform me. The previous behavior and some error
messages are used with -kc compiler switch
* harbour/source/rtl/symbol.prg
* harbour/source/rtl/tobject.prg
! eliminated limitations in number of constructor parameters
(new syntax with passing optional parameters used)
