Description Agostino Sarubbo gentoo-dev 2020-10-26 07:01:55 UTC

Issue: dev-ml/ocamlnet-4.1.8 calls cpp directly.
Discovered on: amd64 (internal ref: ci)

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] and set the CPP variable to x86_64-pc-linux-gnu-gcc -E.
