Nope, you have a problem with command.com or cmd.exe :)

Try single quotes, and/or try double percent sign.  You may need to experiment
a bit:

GPRINT:a:LAST:'Current:%8.0lf'
GPRINT:a:LAST:'Current\:%8.0lf'
GPRINT:a:LAST:'Current\:\%8.0lf'
GPRINT:a:LAST:'Current\:%%8.0lf'

that sort of stuff.  The problem is not RRDtool.  RRDtool never gets to
see that '%'.  Your OS changes "%8" into the 8th parameter for your script.
