This should make the builder http://lab.llvm.org:8011/#/builders/101/ happy. It uses gcc-9 and not Tip-Of-Trunk as its name indicates BTW. GCC-10 passes all these tests. Fix gcc warnings: -Wsign-compare, -Wparentheses, -Wpragmas. Reviewed By: ldionne, #libc, #libc_abi Differential Revision: https://reviews.llvm.org/D92099
