I have a branch with two src commits that change the default C standard for both userspace and the kernel from C99 to C17. Please do an exp-run with these changes. The two commits can be found on the 'gnu17' branch here: https://github.com/freebsd/freebsd-src/compare/main...bsdjhb:freebsd:gnu17

Some C11 extensions are already used in the base system but implemented on top of GNU C extensions such as _Alignas and _Static_assert. In some cases the fallback versions in cdefs.h are more limited than the native C11 extensions. Even though C11 is the next major version of C, C17 is chosen instead since C17 does not add new features to C but merely fixes defects in C11. It is also well supported by a wide range of clang (7.0.0+) and GCC (8.1+) versions. Along with changing the default, this change also removes explicit requests for c11 via the CSTD variable in various Makefiles. Libraries and binaries for ZFS continue to use c99.
