This looks like an upstream igawk portability bug -- the lines

	processed_program=`gawk -- "$expand_prog" /dev/stdin <<EOF
	$program
	EOF

look like the culprit.  They should be using xargs instead...
This is a Win32 limit, and it has to do with the fact that gawk is invoked
using Win32 calls by default.  There are a few solutions, one of the
easiest being to "mount -X" your /bin and /usr/bin directories.  Or, you
can fix igawk to use xargs and submit your patch upstream... ;-)
