template_db/types.h has a #ifdef NATIVE_LARGE_FILES block that aliases ftruncate64/lseek64/open64 to their un-suffixed counterparts for platforms where glibc's *64 symbols aren't available (notably macOS). The off64_t type itself is still referenced by Raw_File::size(), Raw_File::resize(), Raw_File::seek(), so the block isn't sufficient to compile on Darwin -- Apple clang fails with: error: unknown type name 'off64_t'; did you mean 'off_t'? Adding a 'typedef off_t off64_t;' to the same guarded block fixes the build on macOS. off_t is 64-bit on all 64-bit Darwin targets, so this is semantically identical to the symbols the block already aliases. Activate via CPPFLAGS="-DNATIVE_LARGE_FILES" at configure time.
