The compile failures are fixed by replacing the use of FALSE/TRUE with
false/true as suggested by [1] and/or [2].

A better description is directly from the patch/pull-request ([3]):

  Traditionally, ICU4C has defined its own `FALSE`=0 / `TRUE`=1 macros for use with `UBool`.
  Starting with ICU 68 (2020q4), we no longer define these in public header files
  (unless `U_DEFINE_FALSE_AND_TRUE`=1),
  in order to avoid name collisions with code outside ICU defining enum constants and similar
  with these names.

and explains why it occurred just recently/since the icu bump to version
68-1 ([4])...
