Here are my first patches.

When I tried compiling ap-utils-0.9.5-2002050602 on my Debian woody systems
(both i386 and sparc), I got the following errors and warnings.

#1 and #2 were fatal, #3 is just pickiness from a missing type cast.  What I
don't understand is why errors #1 and #2 occurred.  They seem to come from
local variable declarations that occur in the middle of functions.  I thoug=
ht
that was perfectly legal C, but my version of gcc does not like it.  Has an=
yone
else had similar problems?  Anyway, the code compiled cleanly after I moved=
 the
declarations to the beginning of the code block of the functions.

I have attached the patches I made that let the system compile cleanly.

Roman:  How often will you be posting updated tarballs?  What is your work
schedule like?  Should we be sending small patches that fix one problem at a
time or big patches that include every improvement that we have made?  I ha=
ve a
temporary fix for the ncurses redisplay problem that is worth adding as soo=
n as
possible, but I have not included it in this patch.
