This changes the code to use struct timeval and get_time() on all systems,
which simplifies the code by removing most of the checks for HAVE_GETTIMEOFDAY.
The only user-visible change is that ancient systems without gettimeofday()
will see message like "Server pong from irc.choopa.net 1.0000 seconds" instead
of "Server pong from irc.choopa.net 1.x seconds". And really, I seriously
doubt that there's any systems like that left out there anyway.
Four instances where 'default:' is at the end of a block replaced with
'default: break;' (reported by mscherer).
One typo where [j] should have been [1] (array out of bounds error).
Missing <unistd.h> includes for _exit(), and <string.h> for memcpy().
There's no need for a top-level dummy Makefile - the real Makefile is generated
by configure, and the dummy file only worked on systems that had bash installed
into /usr/local/bin anwyay.
