Take a look at your C compiler manual, under "isspace".
Now, the global C locale it uses isn't the same as the the global
C++ locale obtained by "std::locale()"; and the C isspace takes an
int, not a char; but overloading isspace on int and char alone
would only have added to the confusion.

Incidentally, the "const" qualifiers in CD2 were a typo, fixed
in FDIS.

I'm glad to see somebody reading the locale chapter.  See
http://www.cantrip.org/locale.html for some more information.

I was looking at the standard isspace function, and I noticed that the
version I have (CD2) doesn't list any of the character classification
functions as taking a default locale argument, though it does contain a note
(in section 22.1.1.2) that std::locale::locale() "is  commonly used as the
default value for arguments of functions that take a const local &
argument."  The implementation of the STL that I use does in fact provide
locale() as the default value for the locale argument to the character
classification functions, but I'm wondering if it's standard-conforming for
it to do so.  It's certainly sensible behavior, and behavior that I'd like
to depend on.  Does anyone know why it wasn't included in the standard (or
did it make it after CD2?)

Thanks,
- Brad
