Compilation fails b/c of -Werror about shellinabox HOT 3 CLOSED

with shellinabox-2.4.tar.gz

In general -Werror is a great option as it forces code to be written more 
cleanly and
portably. In most cases, compilers only warn about code that is rather suspect. 
So,
it makes sense to avoid these issues.

The problem happens when compilers invent new experimental and aggressive 
warnings,
and distributions then decide to crank up the default warning level past the
recommended settings. Ubuntu for some reason decides to ship with "-Wformat=2" 
by
default. Normally, "gcc" does not turn on this warning, as it is known to 
generate a
large number of false positives (as you just discovered, yourself).

I implemented some work-arounds that should tell the compiler that no warning is
necessary. I tested compilation with "-Wformat=2" and it now passes. This code 
is now
in Subversion.

But it is possible that Ubuntu turned on some other aggressive warnings that 
trigger
in other parts of the code. If so, please let me know and I'll add work-arounds 
for
those, too.
