Changing the behavior of say -lpthread on the command line is a bad

users to do
-Wl,--push-state,--no-as-needed ... -Wl,--pop-state
whenever they really mean to link some library is too hostile.
My understanding is that at least Debian and SUSE have defaulted to
--as-needed for years, and probably more distros do as well... so
presumably most problems should have been shaken out already. Is anyone
familiar with the status of --as-needed in other distributions?
If Fedora and RHEL are the only major distros that are different, then
that argues in favor of adopting this change, so that developers using
Fedora don't accidentally write programs that are broken on other
distributions. I know I've been stung by this in the past, when an
application I developed on Fedora failed to link on Debian....
