# SYNOPSIS
#
#   AX_WITH_DMALLOC
#
# DESCRIPTION
#
#   Let the user enable/disable support for the dmalloc library available
#   from <http://www.dmalloc.org/>.
#
#   The macro adds the command-line flag "--with-dmalloc". Furthermore,
#   "-IPREFIX/include" will be added to "$CPPFLAGS", "-LPREFIX/lib" to
#   "$LDFLAGS", and "-DDEBUG_DMALLOC" and "-DDMALLOC_FUNC_CHECK" to
#   "$CPPFLAGS".
#
#   To enable dmalloc support in your code, add the following snippet to
#   your header files:
#
#     #ifdef DEBUG_DMALLOC
#     #  include <dmalloc.h>
#     #endif
