Hello,

I am trying to run the embedded program at Standalone Programs (GNU Octave
(version 6.4.0)) <https://octave.org/doc/v6.4.0/Standalone-Programs.html> -
attached.

When I execute the program using .exe created using mkoctfile
--link-stand-alone embedded.cc -o embedded.exe

I get the following error. My computer is *Windows 10*, Gnu Octave v6.4.0.
This was working in the previous version v 6.2.0. Could you please guide.
