dnl This tries to do the "right thing" to locate the boost include files.
dnl If the user explicitly specified --with-boost-include-dir=<foo>
dnl we believe them and use it. Otherwise,
dnl
dnl We look for boost/shared_ptr.hpp in the "normal places". That is,
dnl wherever AC_CHECK_HEADER looks. If the boost includes are in /usr/local/include
dnl this step will find them.
dnl
dnl Otherwise, we check to see if the boost stuff was installed in a version-specific
dnl directory under /usr/local/include. These look like: /usr/local/include/boost-1_33_1
dnl If there's more than one version installed, we select the
dnl lexicographically greatest one.
dnl
dnl If none of these work, we bail.
