 * When version numbers change here, must also go into the following files
 * and update the version numbers:
 * library/init.tcl     (only if major.minor changes, not patchlevel)
 * unix/configure.in
 * win/makefile.bc      (only if major.minor changes, not patchlevel)
 * win/makefile.vc      (only if major.minor changes, not patchlevel)
 * win/README
 * win/README.binary
 * mac/README
 * The release level should be  0 for alpha, 1 for beta, and 2 for
 * final/patch.  The release serial value is the number that follows the
 * "a", "b", or "p" in the patch level; for example, if the patch level
 * is 7.6b2, TCL_RELEASE_SERIAL is 2.  It restarts at 1 whenever the
 * release level is changed, except for the final release which is 0
 * (the first patch will start at 1).

 * and procedure declarations, that occur below.

 * Definitions that allow Tcl functions with variable numbers of
 * arguments to be used with either varargs.h or stdarg.h.  TCL_VARARGS
 * is used in procedure prototypes.  TCL_VARARGS_DEF is used to declare
 * the arguments in a function definiton: it takes the type and name of
 * the first argument and supplies the appropriate argument declaration
 * string for use in the function definition.  TCL_VARARGS_START
 * initializes the va_list data structure and returns the first argument.

 * Macros used to declare a function to be exported by a DLL.
 * 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
 * and DLLEXPORT macros to be nonempty. To build a static library, the
 * 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.

 * values are kept consistent unless some C code sets interp->result
 * directly. Programmers should use either the procedure Tcl_GetObjResult()
 * or Tcl_GetStringResult() to read the interpreter's result. See the
 * SetResult man page for details.
 * Note: any change to the Tcl_Interp definition below must be mirrored
 * in the "real" definition in tclInt.h.
 * Note: Tcl_ObjCmdProc procedures do not directly set result and freeProc.
 * Instead, they set a Tcl_Obj member in the "real" structure that can be
 * accessed with Tcl_GetObjResult() and Tcl_SetObjResult().

 * When a TCL command returns, the interpreter contains a result from the

 * this result, the command procedure returns an integer code, which is 
 * one of the following:
 * TCL_OK         Command completed normally; the interpreter's
 *                result contains   the command's result.
 * TCL_ERROR            The command couldn't be completed successfully;
 *                the interpreter's result describes what went wrong.
 * TCL_RETURN           The command requests that the current procedure
 *                return; the interpreter's result contains the
 *                procedure's return value.
 * TCL_BREAK            The command requests that the innermost loop
 *                be exited; the interpreter's result is meaningless.
 * TCL_CONTINUE         Go on to the next iteration of the current loop;

 * The following structure represents a call frame, or activation record.
 * A call frame defines a naming context for a procedure call: its local

 * the naming context for a namespace eval or namespace inscope command:
 * the namespace in which the command's code should execute. The
 * Tcl_CallFrame structures exist only while procedures or namespace
 * eval/inscope's are being executed, and provide a Tcl call stack.
 * A call frame is initialized and pushed using Tcl_PushCallFrame and
 * popped using Tcl_PopCallFrame. Storage for a Tcl_CallFrame must be
 * provided by the Tcl_PushCallFrame caller, and callers typically allocate
 * them on the C call stack for efficiency. For this reason, Tcl_CallFrame
 * is defined as a structure and not as an opaque token. However, most
 * Tcl_CallFrame fields are hidden since applications should not access
 * them directly; others are declared as "dummyX".
 * WARNING!! The structure definition must be kept consistent with the
 * CallFrame structure in tclInt.h. If you change one, change the other.
