NetBSD/othersrc d5e8d69 — libexec/tnftpd configure configure.in, libexec/tnftpd/build-aux config.sub config.guess
Overhaul to use autoconf 2.61 instead of autoconf 2.13.
Notable differences:
* --with-pam to enable PAM.
* --with-skey improved.
* build-related auxiliary files now in ./build-aux/
* large-file support should be better detected
* use autoconf 2.61 macros to detect struct members, declarations, types (etc).
* remove support for SOCKS for now (until test systems are available)
* use #if defined(foo) rather that just #if foo.
* always use our arpa_ftp.h rather than trying to detect if FTP_NAMES works.
