* unix/configure.in: The change below reveals that the public

        data type Tcl_StatBuf relies on config information.  For now,
        disabled the use of the tclConfig.h file until its full impact
        on Tcl's interface can be assessed.

        * unix/configure:       autoconf-2.57

        * generic/tcl.h:        Moved the #include "tclConfig.h" out of

        * generic/tclPort.:     the public interface, and having it there
        breaks compiled against uninstalled Tcl and extensions using
        autoconf-2.5*.
