Proposal: ByteString based datagram communication (Ticket #1238 )

[Robert Marlow]

Gah, I tried that a couple of times and it made no difference. I tried
it again after getting your email and it did something different. Your
email must have been the magic key it was waiting for. Computers can be
mysterious.

Anyway, the difference unfortunately isn't that it now works. Instead it
spits the same error it gave me when I tried running hsc2hs-hugs on
BSD.hsc directly:

$ runhugs -98 ./Setup.hs build
Preprocessing library network-2.0...
Network/BSD_hsc_make.c:1:49:

compiling Network/BSD_hsc_make.c failed
command was: /usr/bin/gcc -c -I/usr/lib/hugs/include -Iinclude
Network/BSD_hsc_make.c -o Network/BSD_hsc_make.o
./Setup.hs: got error code while preprocessing: Network.BSD

Any ideas?
