warnings when using cctype and tolower.

[Lars Gullik Bjønnes]

I am not really sure if this is somethaing that should be fixed up in
cctype or in ctype.h.

I am on a glibc 2.1.1 system running Redhat.

When using tolower and compiling with -ansi -pedantic -Wall I get a
lot of warnings about "brace groups" not beeing allowed in
expressions.

A scan of ctype.h found that __tobody was to blame, and I rewrote this
for __cplusplus to be a inline function instead.

So Q is, where to do the real fixup?
