The 1.4.12 release always appends the port to the "Host:" header field
(if the "-H" option is specified), older and newer releases only do that
if a non-default port is used.

This is the header generated by check_http.  As you can see, it doesn't
include a Host: header field at all.  At least the 1.4.14 release (which
you seem to use) would *only* omit the Host: header field (and request
HTTP/1.0 instead of HTTP/1.1) if you *don't* use the "-H" option.
Therefore, I cannot really believe that this is the output you got from
running the above command line.
