   本程序用于解决将BBS站从Solaris 2.7 for X86转到Solaris 2.7 for
   SPARC系统中出现的.PASSWD文件不兼容问题本程序在SUN Ultra 1工作
   站上用gcc 2.95.2 for Solaris 2.7编译通过
    
    0. cd bbssrc/util/local_utl/
    1. gcc -O -Wunused -I../include -I../../include -o convert convert.c \
    ../../src/record.c -lucb
    2. cp /export/home/bbs/.PASSWDS PASSWDS
    3. ./convert
    4. cp PASSWDS.new /export/home/bbs/.PASSWDS
    5. 清除共享内存或者重新启动工作站后新.PASSWDS生效

    本程序由西南交通大学BBS系统站长Jesse，电子科技大学flanker，CuteGuy的convert.c
    (用于解决将BBS站从Linux 2.0.X转到Solaris 2.5/2.6 for SPARC系统中出现的.PASSWD
    文件不兼容问题)稍做修改，并参考FB2000V1219的repass.c
    
    谢谢各位大虾们的帮助和启发
