Yep, I know what to include for a Linux program.

Yep, that too! ;)

Very weird

This shouldn't pose a problem since I've configured my ARM as
little-endian.  However, htons (), htonl (), etc should solve that
problem anyhow, shouldn't it?  I mean as far networking code goes that
is.  I would obviously have to be careful about data types between the
two if they were different.  It's nice to have the ARM with 32-bit
little-endian!  Makes my life a lot easier since I'm sending data to a
PC.

I would imagine it is faster using Linux.  


What about threads?  How do those work under Linux?  Are they similar at
all?
