--- Comment #244 from John Buddery <jvb at cyberscience dot com> --- I tried a gcc 11 build with patched 2.30 binutils and it worked. I also tried building binutils 2.36 with just /opt/aCC/bin and no gcc. I didn't get any gnu99 errors, but it did fail because plugin-api.h couldn't work out the endianism. Configuring with: CFLAGS="-O -D__BIG_ENDIAN__=1" ./configure --prefix=/u sr/local/binutils-test --enable-obsolete allowed gas to build, but the build then failed later on in libctf. It looks like libtool is inserting +Maked into the command line for some reason, which breaks things. I don't know if this gas build would work for gcc, probably it would have the same issues as a 32 bit gcc build. +DD64 might fix this. Probably not worth updating though just for gcc if you have a working 2.30 build, since that works OK.
