Without looking at the sources, I'd guess that since the port was done 
for DJGPP v1.x, it doesn't use the filesystem extensions feature 
introduced with v2.0.  I suggest to whoever is interested to check out 
the filesystem extensions and implement TCP/IP support on that level.  If 
you do this, all the rest of I/O (including `select') is taken care of 
automagically for you.  It's an incredible tool for extending DJGPP, 
believe me.  (Thank you, DJ, for including it!)
