+ * generic/tclStrToD.c: Made code more portable by finding a
+ workaround for MSVC's 'volatile' issue that
+ does not require conditional compilation.
+ * win/tclWin32Dll.c (TclWinCPUID): Removed structured event
+ handling from the GCC code
+ since (a) bad code is generated
+ by the instruction scheduling
+ with -O2, and (b) it's not
+ needed on any reasonably modern
+ CPU.
