You're right.  That's easier to understand.  Here's an improved, but still
not quite beautiful solution:



AC_ARG_ENABLE(deprecated,
  [  --enable-deprecated     Include deprecated code [not included by default]],
  if test "$enable_deprecated" = y || test "$enable_deprecated" = yes; then
    debug_deprecated=0
  else
    debug_deprecated=1
  fi,
  debug_deprecated=1)

AC_DEFINE_UNQUOTED(SCM_DEBUG_DEPRECATED, $debug_deprecated,
  [If 1: don't include deprecated code to help get rid of references to it.])



Still, does somebody know about a better autoconf way (for example a
special macro) to realize the following:

- if some feature is enabled, have the macro be defined as 1, otherwise as 0
- the same, but vice versa, like in the above example.

If we go ahead with SCM_DEBUG_ options in that way, this will become a
common pattern.
