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

the most interesting changes go about windows-targets - where the default_prefix is set to /programs, and quite some directories are aliased: sbindir := libdir := bindir and the docprefix-defaults are also a bit different, even on FHS2-compliant systems where the mandir is going to $prefix/man only if prefix=/usr, otherwise they shall go to $datadir/man. We use an extra docprefix to express it which is either defined as being prefix or datadir. not SUBSTed here.
