##  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 test it is likely because the header is a
##  C++ header and it isn't properly guarded by the U_SHOW_CPLUSPLUS_API macro.
##
##  If a header fails the cppguardtest test it is likely because the header doesn't
##  include the utypes.h header first *before* using the macro U_SHOW_CPLUSPLUS_API.
##
##  If a header fails because it is deprecated, add it to the 'dfiles.txt'
##
##
