windows host: no mmap

[matu3ba]

Unfortunately mmap does not exist on Windows (yet) (Zig falsely has mmap in os.zig and the posix things did not get moved to posix.zig yet), so I get (even when targeting windows-gnu, but also for windows-native:

As far as I understand, Memory mapped files Windows have a higher abstraction necessary for usage (at least the stable api).

Thanks, I’ll take a look soon (also happy to review a PR if you’re so inclined).

Perhaps I should add cross compiling for Windows to the CI.

@matu3ba Can you try https://github.com/gpanders/ztags/pull/8 and see if it runs ok on Windows? Unfortunately I've so far had no success getting a Windows VM up and running.

Should be fixed by 09f0a8d966d3bf3f98b2f49e919510b4881a704d.
