You better fulfil your claim "LTP scripts are written to be POSIX 
complaint" before complaining about shells being unhappy with your 
script. E.g. where in IEEE 1003.1-2004 is the "local" you use specified?

Or instead of working on making your script using only the stuff 
specified in IEEE 1003.1-2004 you could simply replace the #!/bin/sh at 
the top with a #!/bin/bash and everbody will be happy.
