I can't offer any immediate help with this but I want the same thing. At
some point, we're planning on funding some extensions into GCC or whatever
reasonable C compiler is around:

    - associative arrays as a builtin type

      {
                assoc bar = {}; // anonymous, no file backing

          bar{"some key"} = "some value";
          if (defined(bar{"some other value"})) ...
      }

    - regular expressions

      {
                char *foo = "blech";

          if (foo =~ /regex are nice/) {
                  printf("Well isn't that special?\n");
          }
      }

    - tk bindings built in

and then we'll port BK to that compiler. It's likely to be GCC because we
want to support all the different architectures but if a kernel sponsered
cc shows up we'll happily throw money at that.
