* generic/tclDate.c:
* unix/Makefile.in: fixed make gendate to swap const with CONST so it uses the Tcl defined CONST type [Bug: 3521] * generic/tclIO.c: removed panic that could occur in FlushChannel when a "blocking" channel would receive EAGAIN, instead treating it the same as non-blocking. [Bug: 3773] * generic/tclUtil.c: fixed Tcl_ScanCountedElement to not step beyond the end of the counted string [Bug: 3336]
