Follow-up Comment #3, sr #111048 (group autoconf): I agree, it's not so easy.
On CMake side, I think they are considering adding an "escape hatch" that would not go unnoticed either. For Autoconf, maybe we could add a separate macro (with a very explicit name) for syntax checks like "case 0 ... 5". A malicious contributor would have a harder time explaining why they would create a syntax check for checking the availability of a system feature like landlock, as was the case with XZ Utils. https://www.man7.org/linux/man-pages/man7/landlock.7.html My 2 cents... _______________________________________________________ Reply to this item at: <https://savannah.gnu.org/support/?111048> _______________________________________________ Message sent via Savannah https://savannah.gnu.org/
