Search for version-numbered tclsh? - Mailing list pgsql-hackers

I notice that the recent patch to enforce finding a tclsh broke a couple
of buildfarm machines.  On reflection, I remember that recent Tcl
versions don't automatically create a 'tclsh' symlink, only a
version-numbered program such as 'tclsh8.3'.  I suggest that maybe we
ought to allow that without forcing people to set TCLSH manually.
Perhaps have PGAC_PATH_TCLSH do
AC_PATH_PROGS(TCLSH, [tclsh tcl tclsh8.5 tclsh8.4 tclsh8.3])

or some such.
