True, but SYSINT_BUFSIZE is being declared.
And it's being used on the next line
(line 4602 of tar-1.output).

So why is SYSINT_BUFSIZE "undeclared" later?  It's
a global identifier; once that's declared,
it should never become undeclared.

Could be a compiler bug.

What happens if you remove every line starting with "#"
from tar-1.output, put the result into a file called
"foo.c", and compile foo.c?  Here's what happens on
my Ubuntu 13.10 host when I run "gcc -c foo.c"
(these warnings may be due to architectural differences).
I don't see a problem with SYSINT_BUFSIZE here.
