autoconf and portable programs: the joke

This is not my rant, but I like it:

I have a simple request for you: each time you run into software that does
this idiotic kind of test, please interact with the idiots upstream for
whom all the world is linux, and try to get them to replace their "joke"
of an autoconf macro with actual genuine tests that actually CHECK FOR THE
FUCKING FEATURE.
