<stikonas>yeah, Guix signature checking mechanism is quite good...

<stikonas>(since it prevents downgrade attacks)

<stikonas>if I remember correctly, Gentoo has slightly simpler check which is vulnerable to downgrades

<stikonas>fossy: so I've compared header files in /image and /usr and they seem identical...

<stikonas>so I think there is probably some hardcoding in binaries

<fossy>for gcc?

<stikonas>well, I've built m4 musl and gcc

<stikonas>nothing else (started with /image prefix, built until gcc)

<stikonas>and then /usr prefix already could reproduce the problem

<stikonas>but all the musl and gcc header files were identical

<stikonas>it might be that something is going on with libgcc

<stikonas>libgcc is used for basically all binaries

<stikonas>(but not for musl and I guess not for gcc)

<stikonas>fossy: oh it's actually libiberty

<stikonas> /image # grep -r sys_errlist *

<stikonas>Binary file lib/mes/libc.a matches

<stikonas>and in /usr

<stikonas>there are no matches

<stikonas>oh, that might be red herring... I might not have installed everything necessary in /usr

<stikonas>fossy: can you try if touch /usr/lib/musl/gcc/i386-unknown-linux-musl/4.0.4/include/syslimits.h helps?

<stikonas>I think it might work for me, but I don't have a proper /usr prefix now

<fossy>stikonas: when I copy gsyslimits.h from gcc source tree to /usr/lib/musl/gcc/i386-unknown-linux-musl/4.0.4/include/syslimits.h ig works

<fossy>thats my hack

<fossy>I can also try an empty file too

<stikonas[m]>I guess both work, if nothing from that file is used
