"UBool" and "TRUE" are defined in "umachine.h", which is a header file for the
"libicu" library.

PostgreSQL includes "unicode/ucol.h", which will include "umachine.h"
(via "utypes.h"), so that should be fine.

Are your libicu headers installed under /usr/include/unicode?
Do you get any messages about missing include files earlier?

Yours,
