Meh. I went to see if I could test that, and didn't get much further
than this on ICU's downloads page:
ICU4C Platform Support
All: Compiler support for C++11 is required for building the ICU libraries.
Some platforms (such as IBM AIX, IBM z and Solaris) may no longer be able
to build ICU until an improved compiler is available.
AFAIK, the only platforms we have where <stdbool.h> isn't used are
PPC Mac, which of course was discontinued around 2008, so there's
zero chance that the compiler supports C++11. Barring somebody
finding evidence of a platform that can run ICU68 and is not using
<stdbool.h>, it's not worth spending time on this combination.
I think we should just s/TRUE/true/ and be done with it.
