I see this error with r11-5147 and no patches applied (so it's pre-existing - somewhere between r11-5028 and r11-5147). e.g. i686-darwin9: make install gives .. g++: error: unrecognized command line option '-no-pie' make[2]: *** [gnat1] Error 1 make[1]: *** [install-gcc] Error 2 make: *** [install] Error 2 x86_64-darwin20 (no configure changes) clang: error: argument unused during compilation: '-no-pie' [-Werror,-Wunused-command-line-argument] make[2]: *** [cc1plus] Error 1 make[1]: *** [install-gcc] Error 2 make: *** [install] Error 2
