 	This is needed for the new integer-reading code in lread.c.
 	It automatically pulls in the following gnulib files, which
 	are used on old-fashioned platforms that don't have strtoumax:
-	lib/inttypes.in.h, lib/strtoimax.c, lib/strtol.c,
-	lib/strtoll.c, lib/strtoul.c, lib/strtoull.c, lib/strtoumax.c,
