// Handle portable symbol export.

// Defining manually which symbol should be exported is required

// under Windows whether MinGW or MSVC is used.

//

// The headers then have to be able to work in two different modes:

// - dllexport when one is building the library,

// - dllimport for clients using the library.

//

// On Linux, set the visibility accordingly. If C++ symbol visibility

// is handled by the compiler, see: http://gcc.gnu.org/wiki/Visibility

#if defined _WIN32 || defined __CYGWIN__

// On Microsoft Windows, use dllimport and dllexport to tag symbols.

#  define RBDYN_PARSERS_DLLIMPORT __declspec(dllimport)

#  define RBDYN_PARSERS_DLLEXPORT __declspec(dllexport)

#  define RBDYN_PARSERS_DLLLOCAL

// On Linux, for GCC >= 4, tag symbols using GCC extension.

#  if __GNUC__ >= 4

#    define RBDYN_PARSERS_DLLIMPORT __attribute__((visibility("default")))

#    define RBDYN_PARSERS_DLLEXPORT __attribute__((visibility("default")))

#    define RBDYN_PARSERS_DLLLOCAL __attribute__((visibility("hidden")))

#  else

// Otherwise (GCC < 4 or another compiler is used), export everything.
