Squash new warnings from VC 7.1 about mixing signed and
unsigned types in comparisons.  I can see why `len` was
changed to size_t here, but don't see why `i` was also
changed.  Change `i` back to int.

Move declaration of local `flags` to top of block.

Revert previous checkin, the check is for <, not ==.  i is unsed in non-debug builds, but is used in debug builds

for 2 different values without changing.  I think this was the intent.
The unused warning only occurs when not building in debug mode.

Fix icc warnings: try to set TCL_UNIX_FD for #if TCL_WIN_SOCKET == TCL_UNIX_FD.  res is not used, add a XXX comment

fail everywhere.

This inappropriately disabled some capabilities which exist.

Now test for readline in -lreadline, if not found there, try it
in -ltermcap only if not in -lreadline.  If both libraries are
required, there will need to be more work, but I'm not sure
under what conditions both libraries would be required.

cases if TERM isn't set or is unknown (perhaps we should only check if
unset or empty?)

Skip the test if TERM isn't set.  This seems to occur when running under
buildbot and presumably cron.
