htonl() ntohl()

As always, you can get information on any DJGPP symbol with info:
C:\>info libc alpha [function-name]

An inline assembly implementation might look like this:
  load number into eax  0123
  swap bytes of ax      0132
  swap shorts of eax    3201
  swap bytes of ax      3210

Or is this already how it works?
