I think the below change to configure.in (and consequent change
to configure) should take care of the FIONBIO problem. It tests
out on my Solaris2.7_x86.  I don't have a convenient Linux box
networked at the moment to check against (maybe next week), but
based on header files it looks okay.  I have to say autoconf takes
a bit of time to get familiar with.  I might do some cleanup work
later on the configure.in to use less sh and more autoconf, though
I doubt the sh constructs cause any problems.

History:
  In order to support a connection timeout, we need to use
non-blocking I/O.  For winsock compatibility we use
ioctl() with FIONBIO.  Solaris says FIONBIO is a BSDism and
has separated those out.  Thus Solaris needs a -DBSD_COMP to
include it (with the caveat that we then can't use termio.h
without conflicts).
