/* The AmigaOS stores file names with regard to upper/lower case, but actions
   on existing files are case independent on the standard filesystems.

   A good example of where this causes problems is the conflict between the C
   include file <string.h> and the C++ include file <String.h>, where the C++
   include file dir is searched first and thus causes includes of <string.h>
   to include <String.h> instead.

   In order to solve this problem we define the macro OPEN_CASE_SENSITIVE as
   the name of the function that takes the same args as open() and does case
   dependent opens.  */
