    AROS Header to define many important types without declaring them.
*/

/* For the fixed-length types */
#include <exec/types.h>

/*
    Many types are expected to be declared in multiple header files. This
    can cause many problems with multiple redefinition. The solution to this
    is twofold.

    1.	Provide a system global version of this type that the headers which
        declare the type can use.
    2.	Make the headers that declare the type declare it safely as
        follows.

	#ifdef	_AROS_SIZE_T_
	typedef	_AROS_SIZE_T_	size_t;
	#undef	_AROS_SIZE_T_
	#endif

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

    These should be the same as the locale.library usage
    They are not though. locale.library uses ULONG for it's character type.
    That is a reasonable assumption, however it makes it difficult for us
    to have the regular assumption about WEOF.

    Not to mention that ISO 10646 defines a 31 bit character set, which
    means that signed representation is quite reasonable.

    The downside of all this is that we will end up with quite a few
    signed/unsigned problems.
