Fails to compile under GCC 11 due to definitions of fserrorno and errornum in multiple files - see bug 705764 and https://wiki.gentoo.org/wiki/Project:Toolchain/Gcc_10_porting_notes/fno_common . The ebuild strips CFLAGS, so -fcommon doesn't help either. Patch attached.

Created attachment 767411 [details, diff] Patch to fix compilation of sys-boot/yaboot-1.3.17-r4 under GCC 11
Upstream PR opened at https://github.com/yaboot/yaboot/pull/2
Hi, this problem prevents me from finishing a Gentoo instalation on a PPC Powerbook G4. Can you please merge the attached patch?
(In reply to Thomas Zimmermann from comment #3) > Hi, > > this problem prevents me from finishing a Gentoo instalation on a PPC > Powerbook G4. Can you please merge the attached patch? FWIW, you can put the patch in /etc/portage/patches/sys-boot/yaboot.
Thanks for the tip. I'll try this.
Did it work for you?
Hi (In reply to Guy Lowe from comment #6) > Did it work for you? Yes, I can confirm that the patch fixes the problem. I copied the patch to the location given in comment 4 and executed 'emerge --ask sys-boot/yaboot'. The package got built and installed.
Again, thanks a lot.
