fix: Windows cross-compilation — unsigned long vs size_t in polynomial_arithmetic.hpp#22072
Merged
Conversation
… header The implementation (.cpp) already uses size_t but the header declared unsigned long. On Linux these are the same type, but on Windows LLP64 unsigned long is 32-bit while size_t is 64-bit, causing -Wshorten-64-to-32 when passing domain.size (size_t) to the parameter.

…l_arithmetic.hpp (#22073) ## Summary Fixes Windows cross-compilation failure on v4-next. Replaces previous PR #22072 which merged without CI validation. The header `polynomial_arithmetic.hpp` declares `unsigned long num_coeffs` but the implementation (.cpp) uses `const size_t num_coeffs`. On Linux these are the same type, but on Windows LLP64 `unsigned long` is 32-bit while `size_t` is 64-bit, causing `-Wshorten-64-to-32` when passing `domain.size` (size_t). This function was removed on `next` before Windows cross-compilation was added, so it was never caught there. It's v4-specific legacy code. Also includes clang-format fix (the previous PR had format violations).

Summary
Fixes the second Windows cross-compilation failure on v4-next (after PR #22056 fixed the first one in file_io.hpp).
