+= is not portable, for a start.

Upstream says:

  "The polipo makefile uses the XFree86 makefile conventions, in which
   CFLAGS contains all the flags passed to the C compiler.  CDEBUGFLAGS,
   PLATFORM_DEFINES and EXTRA_DEFINES are what the user should customise.

   See the /usr/bin/X11/makeg script for an example."
