+# the following is a very strange bug.  CPPFLAGS does not get set correctly
+# if CPPFLAGS is set in the environment.  The top level configure script
+# appends to the CPPFLAGS variable, and then exports it.  This change should
+# be picked up by this configure script, but it is not.  The original 
+# env variable is still used for some reason.  If CPPFLAGS is not set in the
+# environment, everything works fine.
+# Someone more experienced with autoconf will have to come up with a better fix.
