[swift-corelibs-dev] Measurement Formatters & ICU

[Philippe Hausler]

Just because it was super-easy for me to fix:

https://github.com/apple/swift-corelibs-foundation/pull/587

That should allow C++ to be built if desired into CoreFoundation. However round tripping that into the Darwin version of CoreFoundation may be a bit cagey.

I don’t think symbolic conflicts would occur, since, if ICU did eventually introduce the C interface, I assume that it would use just a “u” prefix rather than “ua”. Not sure if that’s what you meant.
