							dnl Locate the Tcl/Tk include files
dnl A hybrid of BLT's approach of looking in lots of places and, if
dnl that fails, just believing what "echo [info library] | tclsh" says.
dnl We play a bit of a trick here piping commands into tclsh
dnl Extra set of brackets hides the Tcl brackets from autoconf m4.
dnl
dnl First, if tclsh is around execute it to make a guess as to where Tcl
dnl is installed, and also to find out if we're using tcl > 7.3.
