From: Akihiro Sagawa <sagawa.aki at gmail.com>

Found with Coccinelle.

v2: Added explicit int return type to avoid these warnings:

tokenize.c:193:15: warning: return type defaults to ‘int’ [-Wreturn-type]
 static inline isDigit(WCHAR c)
               ^
tokenize.c:201:15: warning: return type defaults to ‘int’ [-Wreturn-type]
 static inline isSpace(WCHAR c)
               ^
