Writing Makefile for Tree::M

***
*** This module is written in C++, which is nontrivial to integrate into
*** most pre-built perls. If problems occur during compiling then edit (hack)
***
*** Makefile.PL
*** GiST/Makefile MT/Makefile
***
*** in this order. Especially wautch out for compile and optimization flags.
*** Have fun ;->
