  14     Many types are expected to be declared in multiple header files. This
  15     can cause many problems with multiple redefinition. The solution to this
  16     is twofold.
  17
  18     1.  Provide a system global version of this type that the headers which
  19         declare the type can use.
  20     2.  Make the headers that declare the type declare it safely as
  21         follows.

  28         This is the same method that *BSD uses. I do not know where it was
  29         first applied.

  45     These should be the same as the locale.library usage
  46     They are not though. locale.library uses ULONG for it's character type.
  47     That is a reasonable assumption, however it makes it difficult for us
  48     to have the regular assumption about WEOF.
  49
  50     Not to mention that ISO 10646 defines a 31 bit character set, which
  51     means that signed representation is quite reasonable.
  52
  53     The downside of all this is that we will end up with quite a few
