Well, that doesn't mean that the answer is to use C locale ;-)
However, you could possibly think about making this bit of code
more flexible:
#ifdef KEEPONLYALNUM
#define iswordchr(c) (t_isalpha(c) || t_isdigit(c))
#else
#define iswordchr(c) (!t_isspace(c))
#endif
Currently it seems to be hard-wired to the first case in standard
builds.
