| 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 alig
ned |
| 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) |
