--- 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=3D"-O -D__BIG_ENDIAN__=3D1" ./configure --prefix=3D/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, whi=
ch
breaks things.

I don't know if this gas build would work for gcc, probably it would have t=
he
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.=
