Fix gcc strict-overflow error
Recent gcc (tested with 6.2.1) produces the following error when
compiling with both --enable-warningflags and --enable-debug.
In particular, it seems it is the combination of GCC_STACK_PROTECT_LIB
and -Wstrict-overflow=5 produces the error.
be_local.c:609:4: error: assuming signed overflow does not occur
when simplifying conditional
[-Werror=strict-overflow]
if(count > 0) {
Fix this by changing the type of count from int to size_t, which is
fine since count is never negative.
