+# code invoked by the autoconf generated configure script.  Putting

+# This file switches on the shell variable ${targ}, which is a
+# canonicalized GNU configuration triplet.  It sets the following
+# shell variables:
+
+# targ_obj         object file to include in the link, with no extension
+# targ_machine     ELF machine code for this target
+# targ_size        size of this target--32 or 64
+# targ_big_endian  whether the target is big-endian--true or false
+
+# If the target is not recognized targ_obj is set to "UNKNOWN".
