-	* Makefile.in (lex.c): touch lex.c if gperf failed.
+	* Makefile.in (lex.c): touch lex.c if gperf failed but lex.c exists.
 	  Although this may cause non-updated lex.c,
 	  svn co may generate keywords newer than lex.c especially on
 	  a file system which can record fractional mtime such as XFS.
