depends: remove redundant stdlib option #27721

theuni commented at 5:05 PM on May 22, 2023: member

Like #27628, this is another dependency of #21778, though it doesn't become obvious until used with a newer clang.

This should be a no-op.

Use of -stdlib++-isystem gets rid of any system c++ header include paths and negates the need for this option. In newer versions of clangs the combo produces an annoying warning that actually causes problems during configure.

Well, diffoscope shows only diffs in object files timestamps.

Sorry, I guess I should've said it's a behavioral no-op.
