I was unable to unpack the sources supplied with the "small C
syntax checker program". I tracked down the problem.  The "if"
tests (search for "wc" with your favorite editor), that have,
for example:

if	[ "`wc -c <'Makefile'`" != '    1426' ]

should be replaced by

if	[ "`wc -c <'Makefile'`" -ne '    1426' ]

The problem is that our "wc" program didn't return a number with
4 leading spaces.  Ours returned " 1426 ", instead, causing the
!= test to fail, with the message "Unpack for Makefile failed!".
Using -ne instead of != is an arithmetic test instead of a string
compare test, and fixed the unpack problem.
