Note that Makefile should go since it should be rebuilt from Makefile.in by configure. - start_threads now has HAVE_ALSA_ALSASOUND_H - ptt_unix now uses configure HAVE_SYS_PARAM_H Initial *non production* commit I am a little rusty with it, sorry. --db git-svn-id: svn+ssh://svn.code.sf.net/p/wsjt/wsjt/trunk@58 ab8295b8-cf94-4d9e-aec4-7959e3be5d79
