/* The 32 bit integer types are probably obsolete.

   parallel.c used to use them as buffers for socket I/O, because in the
   protocol on the socket, an integer is represented by 4 octets.  But
   the proper type for that is unsigned char[4], so we changed parallel.c
   to that in September 2004.

   A user of TRU64 4.0f in May 2000 used a -DLONG_32 option, but did
   not indicate that it was really necessary.  After that, Configure
   added -DLONG_32 for all TRU64 builds.  A user of TRU64 5.1A in July
   2003 demonstrated that int is in fact 4 bytes on his machine (and
   long is 8 bytes).  So we removed the -DLONG_32 from Configure.  This
   whole issue may too be obsolete because of the fixing of parallel.c
   mentioned above.
