* MANIFEST: impliment missing functions from <wctype.h>
*
* The use of the long variable is to cope with the possibility of an
* unusual data type having been defined for wchar_t. Unusual types
* have been observed, and often cause unnecessary warnings from
* compilers. The long takes care of it.
*
* Also, the HAVE_ISWPRINT can be false (e.g. on Solaris) but iswprint
* is still available as a macro. Hence, we need to test for the macro
* as well as the function.
