[bug-diffutils] bug#23226: diffutils does not compile with C89 compiler

[Brian Nixon]

Hello,

Hardly a big problem, but the diffutils source contains some variable 
declarations after statements, as follows: 
(line numbers refer to git master as of approx. 2016-04-05T20:20Z)

        src/dir.c:308   int v1 = ...
        src/dir.c:366   for (char const **p = ...
        src/io.c:298    size_t repetitions = ...

This doesn’t correspond with the documentation that states that a C89 compiler 
should be sufficient to compile:

        README:33       This program requires a Standard C compiler (C89 or 
later)...

Regards,

Brian
