warning: extra tokens at end of #ifdef directive
FAIL: 17_intro/headers/c++2020/stdc++.cc (test for excess errors)
Excess errors:
/build/trunk/x86_64-unknown-dragonfly5.9/libstdc++-v3/include/bits/semaphore_base.h:279:
warning: extra tokens at end of #ifdef directive
extra_tool_flags are:
-std=gnu++2a -Wall -Wsystem-headers
The libstdc++-v3/include/bits/semaphore_base.h:279 looks to be a typo:
// Note: the _GLIBCXX_REQUIRE_POSIX_SEMAPHORE macro can be used to force the
// use of Posix semaphores (sem_t). Doing so however, alters the ABI.
#ifdef _GLIBCXX_HAVE_LINUX_FUTEX && !_GLIBCXX_REQUIRE_POSIX_SEMAPHORE
// Use futex if available and didn't force use of POSIX
