53 * WHAT'S UP WITH THIS FILE?
54 *
55 * This is where we define the mystical JRI_PUBLIC_API macro that works on all
56 * platforms. If you're running with Visual C++, Symantec C, or Borland's
57 * development environment on the PC, you're all set. Or if you're on the Mac
58 * with Metrowerks, Symantec or MPW with SC you're ok too. For UNIX it shouldn't
59 * matter.
60 *
61 * On UNIX though you probably care about a couple of other symbols though:
62 *	IS_LITTLE_ENDIAN must be defined for little-endian systems
63 *	HAVE_LONG_LONG must be defined on systems that have 'long long' integers
64 *	HAVE_ALIGNED_LONGLONGS must be defined if long-longs must be 8 byte aligned
65 *	HAVE_ALIGNED_DOUBLES must be defined if doubles must be 8 byte aligned
66 *	IS_64 must be defined on 64-bit machines (like Dec Alpha)
