See dllexport and dllimport here:
    http://gcc.gnu.org/onlinedocs/gcc-3.3.1/gcc/Function-Attributes.html#Function%20Attributes

Note in particular:

    On cygwin, mingw and arm-pe targets, __declspec(dllexport) is
    recognized as a synonym for __attribute__ ((dllexport)) for
    compatibility with other Windows compilers.
