names that have version numbers in it so this macro, DJ_AC_PATH_TCLSH will make the necessary checks. The makefile variable TCLSH is set to the path found. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@18382 91177308-0d34-0410-b5e6-96231b3b80d8

dnl platforms (notably FreeBSD), tclsh is named tclshX.Y - this handles

dnl that for us so we can get the latest installed tclsh version.
