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.
