From fadedac410dcbd4157d8b4ac7bc4d7026a6c18ef Mon Sep 17 00:00:00 2001 From: Jim Meyering Date: Sat, 16 Jan 1999 16:14:56 +0000 Subject: Remove declarations of base_name and get_version. (main): Don't call getenv ("VERSION_CONTROL"); xget_version does it. Use xget_version and function-style XARGMATCH. --- src/ln.c | 21 ++++++++++++--------- 1 file changed, 12 insertions(+), 9 deletions(-) (limited to 'src/ln.c') diff --git a/src/ln.c b/src/ln.c index d15060e85..da70fe7df 100644 --- a/src/ln.c +++ b/src/ln.c @@ -1,5 +1,5 @@ /* `ln' program to create links between files. - Copyright (C) 86, 89, 90, 91, 95, 96, 97, 1998 Free Software Foundation, Inc. + Copyright (C) 86, 89, 90, 91, 95, 96, 97, 1998, 1999 Free Software Foundation, Inc.
