Ok I should have known better than posting this late at night, as it
obviously results in dumb sentences :(

As I pointed in a previous post, it is however set in m4/missing.m4 in
autoconf 2.52 source tree, so it should be possible to use it with plain
autoconf I suppose. missing.m4 also defines AM_MISSING_PROG. I agree though
that the names of these macros sound very automakeish :)
