How hard would it be to patch out the features not supported by base clang?

In my experience porting scientific software to CentOS, which uses very old GCC
suites, it was usually not that difficult (for someone with a good
understanding of C++).

This could be a different matter AFAIK, though.

What exactly is the issue that USE_GCC is working around?  It's not clear from
PR 244603.

I just commented out USE_GCC and the VirtualBox GUI seems to work fine on
12.1-RELEASE.  It also does not depend on llvm70 as 244603 seems to suggest.

LLVM 8 and higher miscompile it due to either a bug in their tail-call
optimization or VirtualBox doing something funky, and one can no longer create
new VMs. I've isolated the LLVM revision that broke it, but I'm still working
out which of the two scenarios is the actual problem.

Sorry- and using newer GCC works around the fact that LLVM7 can no longer
compile against -CURRENT headers.

I see...  I can reproduce that problem here.  Thanks for clarifying.

With portdowngrade I downgraded the port.  I'm on 11.3-RELEASE-p7, and keeping
the rest of packages up to date, while trying the pkg binaries for virtualbox
as they come out.

Used "portdowngrade emulators/virtualbox-ose r526589"

I built it and have been doing a "make reinstall" if things aren't working.
