https://github.com/spacetelescope/drizzlepac/actions/runs/18383687478/job/52376597187?pr=2091#step:9:3240 what tried to inject /Wextra here? It needs to be /W4 (-ish) instead.

Nevermind. Found it in stregion. https://github.com/spacetelescope/stregion/blob/385b599869fcd2a781db9e541280579e540d6863/setup.py#L23-L28

Yeah, this PR is stemmed from

I dunno what's up with the Linux failure. The concerns here is only for Windows:

1. Might not able to do win32 because it tries to build scipy from source for some reason.
2. There are some path handling (and maybe other bugs) that need fixing before this package is compatible with Windows, so it wasn't just blocked by stregion.

Does not sound trivial to fix:

Replacing primary WCS with
	Headerlet with WCSNAME=IDC_2731450pi-HSC30
	Headerlet with WCSNAME=IDC_2731450pi-HSC30
Windows fatal exception: access violation

Turns out https://github.com/spacetelescope/slitlessutils/pull/120 did not need this.
