Build problem - Octave 2.0.16 on NT4/Cygwin

[Charles Hethcoat]

I am having trouble compiling Octave 2.0.16 for Cygwin/WinNT 4.0 SP6.
I have previously compiled and used 2.0.13 (I think it was) for
the same platform with no glitches whatever, so I am left thinking
that something is broken in the 2.0.16 distribution.  I haven't tried
building it on Linux yet.

My gcc is gcc-2.95.2-6.

The build has repeatedly failed at the same point in the makefile.  It looks
like a library problem.  This is the terminal output at the point where it
fails:

make[1]: Leaving directory `/usr/local/octave-2.0.16'
make: *** [all] Error 2

I looked at the the routine /usr/local/octave-2.0.16/src/strftime.c and found 
this:

.
 .
  .
#if HAVE_TZNAME
extern char *tzname[];
#endif
.
 .
  .
#if HAVE_TZNAME
  if (!(zone && *zone) && tp->tm_isdst >= 0)
    zone = tzname[tp->tm_isdst];
#endif
.
 .
  .

The variable tzname (_tzname) is global, and evidently is
supposed to be declared and initialized elsewhere.
The trouble is, I have no idea where to look.

Is there an update, patch, or workaround for this?

Thanks
