cryp.to ac-archive's Miscellaneous (released)

actually used after an AC_ARG_WITH(PKG,...) option-directive, where AC_ARG_WITH is a part of the standard autoconf to define a `configure` --with-PKG option.

this macros works almost like AC_COND_WITH(PACKAGE [,DEFAULT]), but the definition is set to a numeric value. The level of a simple "yes" is given (or assumed "2" if absent), otherwise the level can be given in mnemonic names, being

1 = some
2 = many
3 = all
4 = extra
5 = extrasome more
6 = extramany muchmore much
7 = super everything
8 = ultra experimental
9 = insane

this macro is most handily it making Makefile.in/Makefile.am that have a set of with-level declarations, espcially optimization-levels

the $withval shell-variable is set for further examination (it carries the numeric value of the various mnemonics above)
