// PLATFORM_BYTESWAP defined only if byte order is opposite to that of x86
// PLATFORM_UNIX     defined is OS family is UNIXy (all but windows)
// PLATFORM_DEBUG    defined if building a debug set

// ONE of the following will always be defined
// PLATFORM_linux    linux on x86 or x86_64 (64-bit)
// PLATFORM_irix     SGI IRIX on MIPS
// PLATFORM_win32    Microsoft Windows (32 and 64-bit)

//
//   BBCPP?=g++ -fvisibility=hidden -DPLATFORM_visibility
//
// GCC_HASCLASSVISIBILITY is defined if this facility is available under gcc/unix
//
// perhaps do -fvisibility=hidden and "__attribute__ ((visibility("default")))"
// see:
//   http://gcc.gnu.org/wiki/Visibility
//
// Dont use this yet (well, you can try but you'll see why its not a nice
// drop in solution yet). In particular, the size gains for scopira seem to be
// "only" 10% off, and also, a techniqie to explicity mark whoe classes
// (to include their vtables and typeinfos) NEEDs to be implemented. This may be
// too much of a PITA aswell as reduce are already meager size savings.
