commit 6b39e12ea4d8c029e82ee8495355105100af2d28
Author: Werner Koch <wk at gnupg.org>
Date:   Thu Jun 27 07:29:51 2002 +0000

    * gpgsm.c (main): Use GNUPG_DEFAULT_HOMEDIR constant.
    
    * call-agent.c (start_agent): Create and pass the list of FD to
    keep in the child to assuan.
    * call-dirmngr.c (start_dirmngr): Ditto.
    
    * scdaemon.c (main): Use GNUPG_DEFAULT_HOMEDIR constant.
    
    * assuan-pipe-connect.c (assuan_pipe_connect): No special handling
    for the log_fd and stderr.  Connect stderr to /dev/null if it
    should not be retained.
