Describe the issue:
When compiling current Numpy main (ae13307) on MSVC v141, with pip install -v -v ., I get the following compilation error:
C:\repos\numpy\numpy\core\src\npysort\x86-qsort.dispatch.cpp(651): error C3861: '_knot_mask16': identifier not found
This is with:
Microsoft (R) C/C++ Optimizing Compiler Version 19.16.27045 for x64
If I'm using the 142 toolchain, Numpy compiles to completion:
Microsoft (R) C/C++ Optimizing Compiler Version 19.29.30139 for x64
In both cases:
Python 3.9.6 (tags/v3.9.6:db3ff76, Jun 28 2021, 15:26:21) [MSC v.1929 64 bit (AMD64)] on win32
