This patch adds some wctype builtin functions so we can mark their
attributes. I made them all C99 and "pure".
Bootstrapped on sparc-sun-solaris2.7, no regressions and the new
testcase passes.
Ok for mainline?
Thanks,

Except for iswblank, they should be C94 built-ins (a category we don't
currently have but which can easily be added).
(C94 has the peculiarity that functions with names *not* already reserved
in C90 were only reserved as identifiers with external linkage if some
translation unit includes <wchar.h> or <wctype.h>, so functions such as
wprintf which were added in C94 can only be C99 built-ins. But C90
reserves is[a-z]* and to[a-z]* so this isn't a problem for the wctype
functions in this patch.)

This version of my patch incorporates suggestions by Joseph regarding
the wctype functions and C94.
Bootstrapped on sparc-sun-solaris2.7, the new testcase passes.
Full regtest underway.
Assuming no regressions, ok for mainline?
Thanks,
