    Protect all typedefs with #define __typedef_*

    Revision 1.1  1996/09/13 17:55:10  digulla
    AROS special include file exec/types.h. Supports QUAD and IPTR


    Desc: Data typing - must be included before any other file.
    Lang: english

    This version of exec/types.h does not contain any of the definitions
    of obsolete types (eg SHORT, CPTR, ...). If your code contains any
    of these they should have been changed a long time ago.
