To test this code in the common case of a single-processor machine, a 'testwincpuid' command was added to tclWinTest.c, and a test case in platform.test. Thanks to Jeff Godfrey and Richard Suchenwirth for reporting this bug. [Bug #976722]

Added a check in front of those calls to make sure that the TZ env var hasn't changed since the last call to tzset, and repeat tzset if necessary. [Bug #942078] Removed a buggy test of the Daylight Saving Time information in 'gettimeofday' in favor of applying 'localtime' to a known value.

[Patch 742683] This is a ***POTENTIAL INCOMPATIBILITY*** only for those C programs that embed Tcl, build on Tcl_Main(), and make use of Tcl_Main's former ability to pass a leading "-encoding" option to interactive shell operations. * generic/tclInt.decls: Added internal stub * generic/tclMain.c (Tcl*StartupScript*): table entries for two new functions Tcl_SetStartupScript() and Tcl_GetStartupScript() that set/get the path and encoding for the startup script to be evaluated by either Tcl_Main() or Tk_Main().

Removed the use of goto and streamlined the other parts. * generic/tclExecute.c (TclExecuteByteCode): added check for object equality in the comparison instructions. Added short-circuit for != length strings in INST_EQ, INST_NEQ and INST_STR_CMP.
