  87  * These macros are used to control whether functions are being declared for
  88  * import or export in Windows,
  89  * They map to no-op declarations on non-Windows systems.
  90  * Assumes that tcl.h defines DLLEXPORT & DLLIMPORT correctly.
  91  * The default build on windows is for a DLL, which causes the DLLIMPORT
  92  * and DLLEXPORT macros to be nonempty. To build a static library, the
  93  * macro STATIC_BUILD should be defined before the inclusion of tcl.h
  94  *
  95  * If a function is being declared while it is being built
  96  * to be included in a shared library, then it should have the DLLEXPORT
  97  * storage class.  If is being declared for use by a module that is going to
  98  * link against the shared library, then it should have the DLLIMPORT storage
  99  * class.  If the symbol is beind declared for a static build or for use from a
 100  * stub library, then the storage class should be empty.
 101  *
 102  * The convention is that a macro called BUILD_xxxx, where xxxx is the
 103  * name of a library we are building, is set on the compile line for sources
 104  * that are to be placed in the library.  When this macro is set, the
 105  * storage class will be set to DLLEXPORT.  At the end of the header file, the
 106  * storage class will be reset to DLLIMPORt.
