https://gcc.gnu.org/gcc-13/changes.html https://gcc.gnu.org/gcc-13/porting_to.html Backport upstream patch to gcc 13.2 for RISC-V build issue with gcc 4.9.x: GCC should still build with GCC 4.8.3 or newer [1] using C++03 by default. But a recent change in RISC-V port introduced a C++11 feature "std::log2" [2]. Use log2 from the C header, without the namespace [3].
