 *
 * LOG
 * $Log: sdif_portability.h,v $
 * Revision 3.5  2012/01/02 23:49:08  roebel
 * Base selection of WIN32 specific implementation on definition of macros  WIN32 OR _WIN32. The latter being standard in
 * Visual C++ it is most important to have it.
 *
 * Revision 3.4  2006/12/14 17:21:57  roebel
 * Support universal binaries configuration for mac os x.
 * Use endian.h for endianness determination.
 *
 * Revision 3.3  2006/01/16 18:33:29  muller
 * updated visual studio 7.1 projects in order to build the latest sdif version. (only tested with FTM)
 *
 * it only builds a static library for now.
 * for a DLL we either need a module definition file with the list of exported symbols
 * or something like:
 *
 * #if defined( _WIN32) || defined(WIN32)
 * #if defined(SDIFDLL_EXPORTS)
 * #define SDIF_API __declspec(dllexport)
 * #else
 * #define SDIF_API __declspec(dllimport)
 * #endif
 * #else
 * #define SDIF_API extern
 * #endif
 *
 * and SDIF_API in front of all exported symbols
 *
 * Revision 3.2  2004/07/22 14:47:56  bogaards
 * removed many global variables, moved some into the thread-safe SdifGlobals structure, added HAVE_PTHREAD define, reorganized the code for selection, made some arguments const, new version 3.8.6
 *
 * Revision 3.1  2003/11/07 22:00:48  roebel
 * added preincluded.h replacement to CVS
 *
