[PATCH] build: tail: avoid type/format mismatch warning from gcc

[Jim Meyering]

FYI, I saw this on a 686 system using
gcc version 4.6.2 20111027 (Red Hat 4.6.2-1) (GCC)

tail.c: In function 'fremote':
tail.c:908:18: error: format '%lx' expects argument of type 'long unsigned int',
  but argument 4 has type 'int' [-Werror=format]

Subject: [PATCH] build: tail: avoid type/format mismatch warning from gcc

Without this change, gcc's -Werror=format would complain that
the '%lx' format requires 'long unsigned int', not 'int'.
* src/tail.c (fremote): Use a temporary variable.
