It sounds like you want AC_DEFINE instead.  AC_DEFINE will add the given
variable to your compile line as a -D flag unless you also use
AM_CONFIG_HEADER to send it to config.h or some other config header.  If
you give the initialization value in the optional second parameter of
AC_DEFINE, you don't have to add the variable to acconfig.h.

The following may work, depending on what your trying to do.  You may
have to experiment.

AC_DEFINE(DATADIR, "somedir")
