Request for review (S): 7099454 /bin/sh does not support syntax used in the src/os/posix/launcher/launcher.script shell script

[Robert Ottenhag]

Bengt,

The removal of bashisms looks fine. I also not you remove some multiple definitions of MYDIR and and the usused RUNDIR.

The following changes
  + REL_MYDIR=`dirname $0`
  + MYDIR=`cd $REL_MYDIR && pwd`
should however be written shorter as
  + MYDIR=`cd \`dirname $0\` && pwd`
