+ * Used by Windows, maps to no-op declarations on non-Windows systems.
+ * The default build on windows is for a DLL, which causes the DLLIMPORT

+ * macro STATIC_BUILD should be defined.
+ * The support follows the convention that a macro called BUILD_xxxx, where
+ * xxxx is the name of a library we are building, is set on the compile line
+ * for sources that are to be placed in the library. See BUILD_tcl in this
+ * file for an example of how the macro is to be used.
