Hi Jonathan-
The issue isn’t the variable, really, it’s the functions that are
used in the macros. I ran a scratch build on koji so you can see the
errors in question:
https://koji.fedoraproject.org/koji/taskinfo?taskID=82338440
The build log shows the issue when trying to build block.cpp which
ultimately references the macros which reference the functions in
stdatomic:
/builddir/build/BUILD/swift-corelibs-libdispatch-swift-5.5.2-RELEASE/src/shims/lock.h:304:6:
error: use of undeclared identifier 'memory_order_release'

Well, yes and no. The code I linked to in the pastebin is what
demonstrates the issue. The code in question is Apple’s libdispatch
which I package separately as well as part of Swift. In that
situation they’re using a C++ file that uses the underlying
primitives in stdatomic in macros for their own higher-level
functions, thus why stdatomic is ultimately being invoked.
Does this help?
