Tcl Source Code

	* generic/tclCompile.c:	Make sure SetFooFromAny routines react
	* generic/tclIO.c:	reasonably when passed a NULL interp.
	* generic/tclIndexObj.c:
	* generic/tclListObj.c:
	* generic/tclNamesp.c:
	* generic/tclObj.c:
	* generic/tclProc.c:
	* macosx/tclMacOSXFCmd.c:

	* generic/tcl.h:       fix for [Bug 3288345]: Wrong Tcl_StatBuf
	* generic/tclInt.h:    used on MinGW. Make sure that all _WIN32
	* win/tclWinFile.c:    compilers use exactly the same layout
	* win/configure.in:    for Tcl_StatBuf - the one used by MSVC6 -
	* win/configure:       in all situations.

 * TclSetByteCodeFromAny --
 *
 *	Part of the bytecode Tcl object type implementation. Attempts to
 *	generate an byte code internal form for the Tcl object "objPtr" by
 *	compiling its string representation. This function also takes a hook
 *	procedure that will be invoked to perform any needed post processing
 *	on the compilation results before generating byte codes. interp is
 *	compilation context and may not be NULL.
 *
 * Results:
 *	The return value is a standard Tcl object result. If an error occurs
 *	during compilation, an error message is left in the interpreter's
 *	result.
 *
 * Side effects:
 *	Frees the old internal representation. If no error occurs, then the
 *	compiled code is stored as "objPtr"s bytecode representation. Also, if
 *	debugging, initializes the "tcl_traceCompile" Tcl variable used to
 *	trace compilations.
