CPPFLAGS is for the preprocessor, so setting CPPFLAGS to $CFLAGS is
probably not what you want.

-I flags belong in CPPFLAGS.

-L flags belong in LDFLAGS.

Use CXXFLAGS and CFLAGS for things like -O and -g, and I suppose
-mieee-fp if that is not discovered automatically by the configure
script.

I don't think any variable CXXPP is used in Octave's configure scripts
or Makefiles.
