The script now detects functions in libraries and executables.  It 
supports alternative executables for cases like when one needs to chose 
a compiler from a list (cc, gcc, mingw32-gcc, etc).  2.8K so far, hehe.

Done.  Needs testing though, I couldn't (rather didn't) find a DNS 
server that would fail queries.

Done.  On BSD architecture, libresolv is used to detect the number of 
name servers, query timeout and retransmission count.  On NT, localhost 
is still used as the only server.

This can easily be implemented now that we have the rascal_set_option 
function, though I'm still in doubt whether this is actually necessary.

Done.  Test zero one succeeds, which means that DNS and outgoing 
connections work fine.  Incoming connections have not been yet implimented.

One limitation is that only one worker thread is currently started on 
non-NT architecture.  If anyone knows a way to find out the number of 
CPUs installed, I'd like to hear about it.

This is also mostly done.  I'd like if a native english speaking 
developer could read it and send comments about anything, including 
typos, stylistic and conceptual mistakes.
