Hi,

I'm trying to compile (aka, creating a new pkgsrc) rxvt-unicode.
On the make process, I got the following error :
**********
command.C: In member function `bool rxvt_term::cmd_parse()':
command.C:2587: error: `SIGWINCH' undeclared (first use this function)
command.C:2587: error: (Each undeclared identifier is reported only once for 
   each function it appears in.)

gmake[1]: Leaving directory `/usr/pkgsrc/x11/rxvt-unicode/work/rxvt-unicode-4.0/src'

My Makefile (initially done by url2pkg) looks like :

the command.C SIGWINCH code is :
      if (!IS_CONTROL (ch) || ch == C0_LF || ch == C0_CR || ch == C0_HT)
        {
          if (!seen_input)
            {
              seen_input = 1;
              // many badly-written programs (e.g. jed) contain a race condition:
              // they first read the screensize and then install a SIGWINCH handler.
              // some window managers resize the window early, and these programs
              // then sometimes get the size wrong.
              // unfortunately other programs are even more buggy and dislike
              // being sent SIGWINCH, so only do it when we were in fact being
              // resized.
              if (seen_resize)
                kill (-cmd_pid, SIGWINCH);
            }

reading some issue abot NetBSD ncurses&SIGWINCH, I tried using devel/ncurses but that doesn't solve the problem.
furthemore, changes-2.0.html says :
	March 2004
	libcurses
	add KEY_RESIZE, SIGWINCH handler and support for more colour pairs. [jdc 20040322]

I run NetBSD-2.0RC4/i386.

Any idea what I should do to correct this error ?
Include some libs, or patch configure/command.C in some way ?

TIA,
	Jo
