[Findutils-patches] [PATCH 3/5] maint: avoid -Werror=unsafe-loop-optimizations warning in oldfind

[Bernhard Voelker]

oldfind.c: In function ‘process_path’:
oldfind.c:1445:14: error: cannot optimize loop, the loop counter may overflow 
[-Werror=unsafe-loop-optimizations]
        while (cur_path_size < file_len)
              ^
cc1: all warnings being treated as errors

* find/oldfind.c (process_path): Replace loop by calculation, avoiding
the offending loop at all.
