From bbc43ca6ae0bec4f64e69c9cd4c967005d6470eb Mon Sep 17 00:00:00 2001 From: Mitchell Blank Jr Date: Mon, 21 Dec 2020 12:05:19 +0000 Subject: [PATCH] Fix configure failures with Xcode12 Changes are needed becuase Xcode12 includes a default of -Werror,-Wimplicit-function-declaration which means that even something like calling "exit(0);" is a compile failure if you haven't done a "#include " first (as C99 requires, but most other compilers will just warn about) I don't know if the "long long reliability test 2" test which tries to provoke a crash on a particular gcc 3.3 build still does what it was originally intended to do with my change. Of course, I doubt anyone has tried to use that compiler in years.
