* Part 2 of a failed commit (cvs broke). Original message:Peter Wemm1997-03-131-0/+158

Noticed by: bde The following commits already happened but the log message got lost: Modified Files: gen/Makefile.inc gen/getcwd.c stdlib/Makefile.inc Removed Files: gen/realpath.3 Notes: svn path=/head/; revision=23833
