dnl Some macros to configure with malloc() debugging libraries.
dnl
dnl Main functions:
dnl adl_WITH_MTRACE handle the --with-mtrace option
dnl adl_WITH_DMALLOC handle the --with-dmalloc option
dnl adl_WITH_EFENCE handle the --with-efence option
dnl adl_WITH_MPATROL handle the --with-mpatrol option
dnl adl_ENABLE_MEM_DEBUG handle the --enable-mem-debug option
dnl (i.e. use mpatrol, mtrace, dmalloc
dnl or efence, whatever the first found is)
dnl
dnl Auxiliary functions:
dnl adl_CHECK_MTRACE actually check for mtrace availability
dnl adl_CHECK_DMALLOC actually check for dmalloc availability
dnl adl_CHECK_EFENCE actually check for efence availability
dnl adl_CHECK_MPATROL actually check for mpatrol availability
dnl adl_CHECK_MEMORY_USAGE actually check gcc -fcheck-memory-usage
dnl (can be used with mpatrol, currently
dnl not called)
dnl adl_CHECK_MPATROL_LIBS actually check for libraries needed by
dnl mpatrol.

dnl adl_CHECK_MTRACE([ACTION-IF-FOUND], [ACTION-IF-NOT-FOUND])
dnl Check for mtrace (GNU libc malloc debugging functions).
dnl
dnl This will define HAVE_MTRACE if mcheck.h and mtrace() exists.
dnl
dnl Use this macro in conjunction with the following code.
dnl #if HAVE_MTRACE
dnl # include <mcheck.h>
dnl #else
dnl # define mtrace()
dnl # define muntrace()
dnl #endif
dnl and put the call to mtrace and muntrace where appropriate.
