#define __cpp_lib_constexpr_cmath 202306L
#define __cpp_lib_constexpr_complex 202306L
Requires compiler work, followup to:
- #2530
Note: We are not yet accepting PRs for C++26 features.

Research direction
Start by reading WG21-P1383R2 and the follow-up issue #2530, then compare the requested constexpr changes with the feature-test macros listed in the issue. No source files, tests, or implementation entry points are named; completion would require the compiler work for the C++26 feature, and the issue notes that PRs are not currently being accepted.
