gnuplot_date[] in timestamp.h is empty after "make" in building source from git

[Tatsuro M. <tma...@ya...>]

Hello

I think that it is not a bug but a git trouble.

I checked out git source
git clone https://git.code.sf.net/p/gnuplot/gnuplot-main gnuplot 

and

./prepare
./configure (options)
make

The produced src/timestamp.h is

#ifndef GNUPLOT_TIMEBASE_H_INCLUDED
#define GNUPLOT_TIMEBASE_H_INCLUDED
const char gnuplot_date[] = "";
#endif /* GNUPLOT_TIMEBASE_H_INCLUDED */

I have observed the above on Cygwin and ubuntu 16.04.

What is happening?
