It appears that the gnuplot -V info does not go to stdout or stderr on Windows. See sample tclsh sessuion below:

tclsh
% exec gnuplot -V

However, if I pass a comman via the -e option, I get a response.

% exec gnuplot -e "show version"

This is an actual bug. It is a side effect of the introduction of Unicode capabilities in version 5.2.
The string is output using the Console API instead of C stdio. This should get fixed for 5.2.1.

We are currently in progress of converting the CVS repo to git. So an actual fix might take a bit.

Ethan, could you please move this to "Bugs"?

If you post a patch here I will include it in 5.2.1 regardless of the freeze on cvs/git commits. I plan to prepare the 5.2.1 tarball based on CVS snapshot + last minute bugfixes (2 so far, this would be the 3rd).

Patch attached. I had this already because it also enables auto-rewrapping of lines when the size of the Windows 10 console changes:

* src\win\winmain.c (ConsolePutS, ConsolePutCh): Use standard file IO instead of Console API to enable word-wrapping on Windows 10 and to allow for redirection of stdout/stderr. Bug #1985
