/* When building with MSVC, exporting a symbol means that the object file
   contains a "linker directive" of the form /EXPORT:symbol.  This can be
   inspected through the "objdump -s --section=.drectve FILE" or
   "dumpbin /directives FILE" commands.
   The symbols from this file should be exported if and only if the object
   file gets included in a DLL.  Libtool, on Windows platforms, defines
   the C macro DLL_EXPORT (together with PIC) when compiling for a shared
   library (called DLL under Windows) and does not define it when compiling
   an object file meant to be linked statically into some executable.  */
