[fpc-pascal] Endiannes & programmer's manual - missing compiler define?

[Reinier Olislagers]

Had a look at the Programmer's Manual (April 2011, doc version 2.4)
appendix G (compiler defines)

Saw
ENDIAN_LITTLE
ENDIAN_BIG

Did not see
FPC_LITTLE_ENDIAN
FPC_BIG_ENDIAN

Should that be added?

Also, I'm sure there must be functions to convert endianness - at least
network byte order (big endian) to host order.
I found e.g. Synapse synsock:
  function ntohs(netshort: word): word;
  function ntohl(netlong: longword): longword;
  function htons(hostshort: word): word;
  function htonl(hostlong: longword): longword;

Are there an equivalent RTL/FCL functions?

Thanks,
Reinier
