#582 Release Windows arm64 builds

[Vivek Sharma]

Hello,

Now that the "Copilot+PC"(Windows ARM) laptops are rapidly increasing in market share (Microsoft Surface Laptop, Dell XPS 13, HP OmniBook X 14, and more), are there any plans to provide builds for Gnuplot on Windows arm64?

Please try to add support and builds soon so that Gnuplot can be much more usable on Windows on ARM. Thanks.

Using cross-compilation with MSYS2/CLANG64 I managed to build a first bare (i.e. no additional libraries) version for WOA. Lacking a machine to test on myself, I now have to either find someone willing to test, or get qemu running.

I have uploaded a first testing binary of gnuplot for Windows on ARM to "testing" folder in the files section (indicated by -woa). Please note that this is completely untested. It has no support (yet) for wxt, qt, gd terminals, and does not provide functions which rely on the openspecfun or cerf libraries.

In the meantime I can confirm that it actually works. Qualcomm kindly provided access to its device cloud.

Full support for WOA is now in the master and 6.0 branches. The binaries include (almost) full support for all options normally supported on Windows. This includes the installer. The only exceptions are the amos functions (openspecfun), as I yet have to figure out a way to compile those Fortran routine in a way compatible with clang.
There are testing binaries in the files section, which only lack the (pdf) documentation and the licensing files.
