* Removed internal routine

        TclMathInProgress and Unix implementation of matherr().  These
        are now obsolete, dealing with very old versions of the C math
        library.  Windows version is retained in case Borland compilers
        require it, but it is inactive.  Thanks to Joe English.
        [Bug 474335, Patch 555635].
