problem compiling corebase

[Riccardo Mottola]

Hi,

I'm trying to compile current corebase on freebsd with clang and I get 
the following blocking errors:

CFString.c:1839:11: error: unknown type name 'UNormalizationMode'
CF_INLINE UNormalizationMode
          ^
CFString.c:1845:14: error: use of undeclared identifier 'UNORM_NFD'
      return UNORM_NFD;
             ^
CFString.c:1847:14: error: use of undeclared identifier 'UNORM_NFKD'
      return UNORM_NFKD;
             ^
CFString.c:1849:14: error: use of undeclared identifier 'UNORM_NFC'
      return UNORM_NFC;
             ^
CFString.c:1851:14: error: use of undeclared identifier 'UNORM_NFKC'
      return UNORM_NFKC;
             ^
CFString.c:1869:3: error: use of undeclared identifier
      'UNormalizationCheckResult'
  UNormalizationCheckResult checkResult;

Perhaps it is relevant that cofnigure fails to detect most unicode stuff 
(HAVE_UNICODE_* are all undefined) and thus perhaps that code path 
should be disabled?
