##  THE PURPOSE OF THIS TEST
##
##     This tests all public header files  - as installed.  icu-config needs to be on the PATH
##  
##     To run it simply type 'make check' after ICU is installed. You SHOULD see:
##
##  unicode/uchar.h -	0
##  unicode/uchriter.h -	0
##  unicode/ucnv.h -	0
##
##    .. etc.  Anything other than zero is an error. (except for the deprecation tests, where '1' is the correct value)
##              
##
##  If a header fails the C compile because it's a C++ header, add it to the
##  file named 'cxxfiles.txt' in this directory.
##
##  If a header fails because it is deprecated, add it to the 'dfiles.txt'
##
##
