Fix MacOS X 10.4 compile issues.

configure.in:
    - 10.4 doesn't include libsupc++.a, so we need to use g++ when compiling.

src/Fl_Help_View.cxx:
    - Fl_Help_View::format_table(): missing initialization of font and fsize.

src/Fl_Text_Buffer.cxx:
    - Fl_Text_Buffer::remove_rectangle(): missing initialization of endOffset.

src/Fl_Gl_Window.cxx:
    - Fl_Gl_Window::flush(): use 0xff instead of ~0 for clear_damage() call.

test/keyboard.cxx:
    - Apparently unnamed structs are not supported by Apple's GCC 4.0...
