sigh - we've seen issues with ctype functions before, and I'm just not really
clear on the best way to handle them. It seems that there is some sort of
obfustication going on in the ctype.h header file that somehow filters
down to pain in uclibc/busybox. This work around is as good as any - if
anything, it costs us a few bytes in an extra possibly not needed function,
but thats not so bad.
