echo "dir" | /usr/xpg4/bin/awk -v c=0 '$1 {++c} END {print c}'
0

And with GNU awk for comparison:
echo "dir" | /opt/csw/gnu/awk -v c=0 '$1 {++c} END {print c}'
1

Instead of modifying the awk code to work, use wc -w instead as that
is both adequate and simpler.

Hmm, why "wc -w" not "wc -l", though?  Is somebody squashing a
one-elem-per-line output from ls-files onto a single line?

The old code was trying to skip empty lines.

Ahh, I misread the original.

Your suggestion to explicitly check $1 != "" makes sense to me now.

To be blunt, I do not have much sympathy to those who insist using
/usr/bin versions of various tools on Solaris that are overriden by
xpg variants, but it is somewhat disturbing that the one from xpg4
does not work.
