Versions of GCC earlier than 6 need this change in order to be built by GCC
6 and later. At the time, the fix was backported to GCC 4.9 and GCC 5 but
not GCC 4.8.
Therefore, backport the fix from GCC 4.9 to GCC 4.8.
* gnu/packages/gcc.scm (gcc-4.8)[source]: Apply
gcc-4.8-fix-build-with-newer-gcc.patch.
* gnu/packages/patches/gcc-4.8-fix-build-with-newer-gcc.patch: New file.
* gnu/local.mk (dist_patch_DATA): Add new file.

Hi,
This is the patch I mentioned in my previous email. Despite the subject
and the name of the patch file, this change is necessary but unfortunately
not sufficient to make GCC 4.8 build with GCC 6 or later.
This patch solves the same problem as gcc-4-compile-with-gcc-5.patch and
gcc-4.6-gnu-inline.patch (which are actually the exact same patch).
Regards,
Thiago

Hello,
According to the CI results, gcc-4.8 hasn=E2=80=99t built successfuly in a =
while:
https://ci.guix.gnu.org/search?query=3Dgcc-4.8
I was able to fix the current build failure:

by backporting a patch from GCC 4.9 (which I will send in the next email),
but then I hit another failure:

and so on, for several `std::` functions. Unlike the other old GCC build
failures I=E2=80=99ve investigated recently, I couldn=E2=80=99t find anyone=
else hitting
this specific problem. So we would have to create our own patch to fix it.
This message from Jakub Jelinek about a similar error in some unspecified
package:
https://lists.fedoraproject.org/archives/list/devel@HIDDEN=
/message/Q2U4JFUB5RL7DU2XJZ4BDTRE4PVULOMG/
makes me think that there=E2=80=99s something in GCC 4.8=E2=80=99s libstdc+=
+ (probably
in libsupc++) doing something wrong with <stdlib.h> which trips GCC 6
and later.
However, I don=E2=80=99t think it=E2=80=99s worth making GCC 4.8 build agai=
n. It=E2=80=99s not
supported upstream anymore and if it=E2=80=99s needed in some bootstrap pat=
h,
it=E2=80=99s better to move it to =E2=80=98(gnu packages commencement)=E2=
=80=99 instead. In that
case, instead of fixing this build issue it=E2=80=99s likely better to just=
build
it with a GCC older than version 6.
Is it needed for bootstrap though? The definition of =E2=80=98%bootstrap-gc=
c=E2=80=99
suggests that it=E2=80=99s needed at least for armhf-linux but since aarch6=
4-linux,
powerpc64le-linux and even i586-hurd use GCC 5.5, I suspect it would also
work for armhf-linux as well.
Therefore, my suggestion is to simply remove gcc-4.8.
