# Loading for Tcl -- What Became of It?".  Proc. 2nd Tcl/Tk Workshop,
# New Orleans, LA, Computerized Processes Unlimited, 1994), then we need
# to determine which of several header files defines the a.out file
# format (a.out.h, sys/exec.h, or sys/exec_aout.h).  At present, we
# support only a file format that is more or less version-7-compatible.
