Using auxiliary files such as \`acconfig.h\', \`config.h.bot\'
and \`config.h.top\', to define templates for \`config.h.in\'
is deprecated and discouraged.
Using the third argument of \`AC_DEFINE\' and
\`AC_DEFINE_UNQUOTED\' allows one to define a template without
\`acconfig.h\':
AC_DEFINE([NEED_FUNC_MAIN], 1,
[Define if a function \`main\' is needed.])
More sophisticated templates can also be produced, see the
documentation.
