Issue: dev-libs/uriparser-0.9.5 calls cpp directly.
Discovered on: amd64 (internal ref: ci)
This machine uses GCC-11: https://gcc.gnu.org/gcc-11/porting_to.html
As per QA policy, toolchain tools must not be called directly because they can cause issue in cross-compiling and because is not possible use a different CPP implementation (like clang-cpp). To reproduce, please use sys-devel/gcc-config[-native-symlinks], sys-devel/binutils-config[-native-symlinks].

Related part of the log:
[11/20] cd /var/tmp/portage/dev-libs/uriparser-0.9.5/work/uriparser-0.9.5_build/doc && /usr/bin/doxygen Doxyfile
/var/tmp/portage/dev-libs/uriparser-0.9.5/work/uriparser-0.9.5/doc/preprocess.sh: line 3: cpp: command not found
So it's Doxygen related, not the actual compilation process.
Ago, the issue is fixed upstream now. Personally, I consider the issue and the fix unimportant enough to not cherry-pick the fix to 0.9.5-r1 but rather keep this open until 0.9.6 is released, whenever that is. If you do think that cherry-pick would be the better way to go forward, please let me know. Thanks!
