   I think so. I don't have those problems when compiling with MinGW for Win32,   
   either. It seems it depends on how each compiler implements the strcpy   
   function.   
      
   This may be a possible way to fix the corrupted From field in headers: in   
   nntpserv.c, instead of just removing this line:   
      
    strcpy(mimefrom,&mimefrom[6]);   
      
   Replace it by:   
      
    memmove(mimefrom,mimefrom+6,strlen(mimefrom)-5);   
      
   There could also be issues with the Subject field. The next line:   
      
    strcpy(mimesubj,&mimesubj[9]);   
      
   could be changed to:   
      
    memmove(mimesubj,mimesubj+9,strlen(mimesubj)-8);   
      
   As for the corruption in the body of messages posted with newsreaders that   
   support flowed text (like Thunderbird), I think it may be fixed by changing   
   this:   
      
    strcpy(line,&line[1]);   
      
   to this:   
      
    memmove(line,line+1,strlen(line));   
      
   These patches are for both JamNNTPd and SmapiNNTPd.
