Hello,
I am trying to comile GCC 11.2.0 on msys2 (gcc version 10.3), but when compiling liblto_plugin.dll in stage 3, it says "undefined reference to `stpcpy'".


This GCC configured by ../gcc-11.2.0/configure --disable-multilib --disable-nls --disable-rpath --disable-symvers --disable-win32-registry --enable-languages=c,c++,lto --enable-mingw-wildcard --enable-threads=posix --enable-libgomp --disable-libstdcxx-verbose --enable-fully-dynamic-string --with-build-config=bootstrap-lto-lean --with-system-zlib
