build environment. Because option of ``-traditional'' was added by
jtex-1.52/configure, and failed in build phase.
I found that ``configure'' was broken if we make this ports with
crontab.
In jtex-1.52/configure, next C program was compiled and executed.
With terminal (normal) environment, ioctl was successful. But with
crontab, ioctl was failed.

#include <sys/types.h>
#include <sgtty.h>
main() {
struct sgttyb t;
exit(ioctl(0, TIOCGETP, &t) == 0);
}

I referred configure file which was generated by autoconf ver.2.13
and update jtex-1.52/configure file for ``-traditional'' and unbreak
this port.
