Yes, this works now, and if I change:

   builddir = `pwd`
   AC_SUBST(builddir)
   ...
   builddir = @builddir@

to

   ugh_ugh_autoconf250_builddir = `pwd`
   AC_SUBST(ugh_ugh_autoconf250_builddir)
   ...
   builddir = @ugh_ugh_autoconf250_builddir@

then the --srcdir configure/build works too.  Phew.  Btw, why have
these change in behaviour not been mentioned in the NEWS file?

Ok.  However, it seems that

        STEPMAKE_ADD_ENTRY($2, "$r $3 (installed: $ver)")

should become:
        
        STEPMAKE_ADD_ENTRY($2, ["$r $3 (installed: $ver)"])

in our case, as the second parameter gets eval'ed.

Yes, the idea was to move all kinds of generic functionality to a
library, and have real simple configure.in's.

Ah, I'll have a look.  I suppose that when this was added, autoconf
did not do anything yet for Cygwin, or at least did not do what was
needed.

Thanks!  I think that I've made the most necessary changes in CVS now
(expected to be in 1.7.8), but I would appreciate it if you'd have a
quick look.
