Missing search.h in /usr/include

["Enrico Spinielli" <Enrico dot Spinielli at marconi dot com>]

Hi,
 I am having problems compiling a set of simple C programs for manipulating
HTML and XML, html-xml-utils-2.1.tar.gz from W3C [1] .
The platform I am working on is as follows (result of 'uname -a'):
     CYGWIN_NT-4.0 GEPC4223 1.3.3(0.46/3/2) 2001-09-12 23:54 i686 unknown
The errors I got are related to
     include <search.h>
where search.h is an include file for tsearch, tfind, tdelete, twalk which
are
functions for managing binary search trees [2].
Usually you can find it in /usr/include (at least on a Sun Server I am
workin on)

I thought these functions where part of standard C library and I am
wondering why
they are not part of cygwin distribution (maybe as part of gcc?).

Any help/idea?
Thank you in advance
Bye
Enrico
