Please reformat the ChangeLog entries according to the GNU coding
standards (http://www.gnu.org/prep/standards/).

I don't like using OS-dependent #define's where a functionality-based
#define can do the job.  How about

    +#ifndef INVALID_SOCKET
    +#define INVALID_SOCKET -1
    +#endif

and then use INVALID_SOCKET everywhere?

Also, this:

    +static int remote_desc=INVALID_SOCKET;

is not according to GNU standards: you need spaces around `='.

Your mailer wraps lines, which will cause the Patch utility to fail to
apply the diffs.  Please find a way to not wrap lines in the patch; if
nothing else helps, send it as a binary attachment.

See above.

Please don't add excess whitespace.  (There's a single blank on the
line you modified.)

I don't understand the need for this change.  Can you explain?
child_continue does not promise to return exactly 1 when it fails,
only non-zero.
