You can fix this particular problem by editing the src/network.c file
and replacing the poll() invocation around line 128 with:

   retval=poll(fds->ufds, fds->nfds, timeout<0 ? -1 : 1000*timeout);

...as it is in 4.07's network.c.

I'm not sure about the 4.07 and 4.08 build errors; I might take a closer
look later on.

G'luck,
Peter
