[PATCH] S390: Get rid of format warning in mem.c

[Stefan Liebler]

Hi,

on 31bit s390 i get the following warning/error:
gcc mem.c -c ...
mem.c: In function 'gc':
mem.c:428:4: error: format '%zu' expects argument of type 'size_t', but 
argument 2 has type 'int' [-Werror=format=]
        dbnames[db - dbs]);
        ^
cc1: all warnings being treated as errors


This patch adds a cast to size_t in order to disable the warning.

Ok to commit?

Bye
Stefan
