[Vm-dev] Gnuification fails when compiling unix VM with latest VMMaker source

[Adrian Lienhard]

Hi Subbu,

When I messed with the awk script to find the line break problem I apparently commented out the following line

	FS=" ";

and commented in the line

	# FS="[ 	:]+";

which explains why $NF did not work anymore. Sorry for the noise...

Cheers,
Adrian
