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