+# Use it like:

+#	awk -f gen_errno_tables.awk -v PREFIX=OSF1 netbsd_errno_hdr \
+#	    osf1_errno_hdr

+# It puts results into 'c' and 'h' in current directory, which can then be

+# Note that this script is not meant to generate perfectly pretty output.
+# Wanna be a formatting weenie, hand-edit the output (or make the script
