?S:	This variable holds the base name of a file containing the
?S:	definition of the sys_errnolist array, if the C library
?S:	doesn't provide it already.  Otherwise, its value is empty.
?S:	The following lines should be included in your Makefile.SH:
?S:

?S:	You may define the 'errnolist' variable in your Myinit.U if you
?S:	wish to override its default value "errnolist".

?S:errnolist_SH:
?S:	This is the name of a file which will generate errnolistc.

?S:errnolist_a:
?S:	This is the name of the awk script called by errnolist_SH.

?S:errnolist_c:
?S:	This is the name of a generated C file which provides the

?S:	This is the name of the object file which provides the
