qt5.5.1 移植4412的问题过程

１、编译错误：

../WTF/wtf/unicode/wchar/UnicodeWchar.h: In function 'bool WTF::Unicode::isAlphanumeric(UChar)':

../WTF/wtf/unicode/wchar/UnicodeWchar.h:136:58: error: 'iswalnum' was not declared in this scope
../WTF/wtf/unicode/wchar/UnicodeWchar.h: In function 'bool WTF::Unicode::isDigit(UChar)':
../WTF/wtf/unicode/wchar/UnicodeWchar.h:137:51: error: 'iswdigit' was not declared in this scope
../WTF/wtf/unicode/wchar/UnicodeWchar.h: In function 'bool WTF::Unicode::isLetter(UChar)':

解决：
vi ./qtwebkit/Source/WTF/wtf/unicode/wchar/UnicodeWchar.h
#ifndef Android
/*add by gq start*/
#include <wctype.h>
typedef unsigned short int UChar;
/*add by gq end*/
//# include <wchar.h>
// typedef wchar_t UChar;
#else
 typedef unsigned short int UChar;
#endif
