GeoBase.h is the top level configuration file for the Enlighten SDK.

Its most important task is to examine the compile environment (predefined macros, etc) and determine the OS and compiler settings that inform the code declarations, optimised code paths and so on.

GEO_LITTLE_ENDIAN	Target platform stores data in little-endian format in memory.
GEO_LITTLE_ENDIAN	Target platform stores data in little-endian format in memory.

GEO_LLP64	int is 32 bits, long is 32 bits, size_t is 64 bits (Windows style)
GEO_LP64	int is 32 bits, long is 64 bits, size_t is 64 bits (Unix style)
GEO_MAKE_FOURCC ((Geo::u32)(Geo::u8)(ch0) \| ((Geo::u32)(Geo::u8)(ch1) << 8) \| \ ((Geo::u32)(Geo::u8)(ch2) << 16) \| ((Geo::u32)(Geo::u8)(ch3) << 24 ))	Define a 'fourcc' code - a 4 byte string of chars typically used as an identifier in file format headers.
GEO_MSVC	Microsoft Visual C++ 2008 or later (or Intel C++)
