I remember adding support for manually using --with-tcl-header and
--with-tcl-lib to allow flexibility for dealing with layout oddities. It
seems this support disappeared with this change:

2003-02-12  Bart Veer  <bartv@ecoscentric.com>

        * acinclude.m4: Another attempt at the Tcl macro, to cope with
        cygwin tcl 8.3 and 8.4. Also fix some problems with VC++ builds.

Now those configure command-line overrides are only used for building with
MSVC. Seems like it would be worth reinstating.
