[svn-r3114] Purpose: Fix

Description:
	Dec CC compiler doesn't support some new c++ features.
	Some typos caused compilation erros on Dec Alpha.

Solution:
        - Added macro BOOL_NOTDEFINED to define bool type on Dec
          Alpha (gondolin) since its compiler doesn't support bool.
	- Added macro NO_STATIC_CAST to prevent the use of the new
	  c++ feature static_cast since Dec CC compiler doesn't support.
	- Added const to parameters of some functions to match the
	  functions' declaration and definition.  Typos errors and
	  Dec CC complained.

Platform:
	Solaris (arabica).  Also tried to build on Dec Alpha but still
	not linked due to some missing compiler flags; its compilation
	went fine though.
