dnl @synopsis AM_WITH_MPATROL(DEFAULT)
dnl
dnl Integrates the mpatrol malloc debugging library into a new or
dnl existing project and also attempts to determine the support
dnl libraries that need to be linked in when libmpatrol is used.
dnl
dnl It takes one optional parameter specifying whether mpatrol should
dnl be included in the project (`yes') or not (`no'). This can also be
dnl specified as `threads' if you wish to use the threadsafe version of
dnl the mpatrol library. You can override the value of the optional
dnl parameter with the `--with-mpatrol' option to the resulting
dnl `configure' shell script.
