These are values where some platforms might lose precision.

Thanks. The failing tests are helpful (points out where we should be blocklisting clog on musllinux, cygwin, and pyodide). I wonder if at some point we should adopt the cpython cmath tests with the extensive test cases for at least cdouble.

Reviving this PR; I rebased and force pushed the original commit.

Following the example of #25092, where the complex trig functions were blocklisted for musl, I added the appropriate undefs in npy_config.h for the complex log functions.

The pyodide tests also pass now, since emscripten uses musl.

The failure of the freebsd_test job is not related to this PR: "Not enough compute credits to prioritize tasks!"

Also block the use of the provided complex log functions on cygwin. cygwin uses newlib, and newlib's implementation of the complex log is the same naive implementation as that of musl.
