Description Linn cendio 2021-09-17 17:18:09 CEST 
Ran in to this issue when trying to update gcc in cenbuild on Fedora 34. 

Running 'rebuild' results in a build failure, and when looking in /home/cendio/cenbuild/repo/rpmbuild/build.log I see this error:

> ../../gcc/reload1.c: In function 'void init_reload()':
> ../../gcc/reload1.c:115:24: error: use of an operand of type 'bool' in 'operator++' is forbidden in C++17
>   115 |   (this_target_reload->x_spill_indirect_levels)
>       |   ~~~~~~~~~~~~~~~~~~~~~^~~~~~~~~~~~~~~~~~~~~~~~
This error will likely happen on all distributions where we try to run .c-files with a too high version of C++.

How to reproduce:
1. Update gcc in cenbuild
2. Run 'rebuild'
