[FEEDBACK] Issue with fd_set, FD_ZERO, FD_SET, FD_SETSIZE : Cygwin

[Eliot Moss]

Ok ... assuming the "Modern C" is more or less POSIX based and
does not use things outside the realm of what cygwin supplies,
I think the answer is straightforward:

Make sure you install every program and every library that the
book uses.  There's not really such a thing as a "full install"
for Cygwin (and it would huge anyway), so you'll have to figure
out what going through the book demands.  Fortunately, you can
somewhat do that as you go, finding packages that need to be
installed.
