This fix is insufficient on older releases of OpenServer -- h_errno
first showed up in <resolv.h> in 5.0.4, I believe.  I had to patch
HTTCP.c so that it explicitly declares `extern int h_errno;' -- just
like configure's new h_errno test program does.  In general, the actual
implementation code should be as close as possible to what configure is
testing for.
