Hello Heiko,

generally speaking, it is not enough to set CPPFLAGS.  You should rather
configure with something like

     --with-libgmpxx-prefix=/home/heiko/mw32htools

See README.configure for more details.
All the best,

     Roberto

P.S. Note that in the next PPL release the --with-libgmpxx-prefix will
      be substituted with --with-gmp-prefix.
