[vtkusers] Borland link error with vtkTkRenderWidget etc...

yes, there are some fixups needed to get it going, some functions in 
tk82.lib have underscores where they're not wanted and you need to play 
with implib and impdef to get rid of them
I use this batch file to get stuff linked correctly

@echo off
set todir="C:\Program Files\Tcl\bin"
cd /d %todir%

impdef tcl82.def tcl82.dll
c:\bin\util\sed "s/^    /    _/" tcl82.def > tcl82bcb.def
implib -c tcl82.lib tcl82bcb.def

impdef tk82.def tk82.dll
c:\bin\util\sed "s/^    /    _/" tk82.def > tk82bcb.def
c:\bin\util\sed "s/_TkWinChildProc/ TkWinChildProc/" tk82bcb.def > tk82bcb2.def

implib -c tk82.lib tk82bcb2.def

copy *.lib ..\lib\

pause

but it may not work for you and I'm afraid you'll have to play around and 
experiment lots. also make sure various exports from tclutil.cxx and 
suchlike are defined correctly, if you're using pcmaker, then probably it 
won't work.
