some Makefile and hints tinkering

Browse Source 
1. remove all window interface bits from compiler.370, and have
   the preceding include files set some variables to control
   the behavior of compiler.370 when it comes to c++.
2. some more common Makefile lines into sys/unix/hints/include/multiw-3.370.
3. make it so you can pass cppregex=1 on the Make command line to build with
   sys/share/cppregex.cpp instead of posixregex.c
4. fix sys/share/cppregex.cpp so that it will build with clang compiler
   (required an additional header include). I don't know if it would have
   worked with g++ without that change. The include can be placed into an #ifdef
   block if there's an issue with the change on other compilers.
5. Anything that needs to compile using c++ (Qt, sys/share/cppregex.cpp) can
   just ensure that CPLUSPLUS_NEEDED Makefile variable is set above the lines
   in compiler.370 to ensure that things get set up for c++. It no longer
   checks specifically for Qt. That is what sys/unix/hints/include/multiw-2.370
   does now.
