Moved initialization of TIADebug from Console to Debugger, since the Console
doesn't really need to know about it, and it belongs to the debugger anyway. Fixed some makefile issues: Pure C programs were being compiled with 'cc', when 'g++' (or equivalent) should have been used. Only pre-define the compiler flags to include '-O2' if the user doesn't have a CXXFLAGS env variable set. Sometimes I want to use '-g', and in that case I want to override the internal '-O2'. Fixed TIASound code to not use its own type definitions, and instead use the ones from bspf.hxx. Eliminates requirement of specifying -DWIN32, even when the host system wasn't Win32. git-svn-id: svn://svn.code.sf.net/p/stella/code/trunk@583 8b62c5a3-ac7e-4cc8-8f21-d9a121418aba
