   	src/sbbs3/chk_ar.cpp client.h mailsrvr.cpp main.cpp sbbsdefs.h userdat.c   
   userdat.h   
   Log Message:   
   Treat user numbers a 32-bit signed integers, everywhere   
      
   we had mix of signed/unsigned and 16 and 32-bit integer representations of the   
   user number.   
      
   I somehow ended up with a 4GB (4294967296 byte) user.tab file today and don't   
   have an exact smoking gun but the conversions (mainly in userdat.c) between   
   unsigned 16-bit and signed 32-bit representation of the user number had me   
   suspicious.   
      
   Perform some userbase data file and index file sanity checking upon startup   
   of the terminal server thread and fail with critical error if anything seems   
   amiss (indication of corruption).
