Created attachment 196985 [details] Makefile.diff The warning is caused by another exit(3) definition in configure (without _Noreturn attribute); it may be fixed by running ln -s ${WRKSRC}/BuildTools <into all directories with configure.ac> && 'autoreconf -fi -I${WRKSRC}/BuildTools', but 'sed' approach seems to be faster and less complicated. While here, replace manual stripping with INSTALL_TARGET=install-strip.
