dnl This macro defines (with AC_DEFINE) VARNAME to the expansion of the DIR
dnl variable, taking care of fixing up ${prefix} and such.

dnl Note that the 3 argument form is only supported with autoconf 2.13 and
dnl later (i.e. only where AC_DEFINE supports 3 arguments).

dnl AC_DEFINE_DIR(PROG_PATH, bindir, [Location of installed binaries])

# fine, but in subdirectories relative pat needs to be adapted.
# - calling $top_srcidr/$ac_aux_dir/missing would success if $srcdir is
# relative, but fail if $srcdir is absolute
# - conversly, calling $ax_aux_dir/missing would fail if $srcdir is
# absolute, and success on relative paths.

# If you use this macro, you should check after calling it whether the C
# compiler has been set to accept ANSI C; if not, the shell variable
# @code{am_cv_prog_cc_stdc} is set to @samp{no}. If you wrote your source
