[Ohrrpgce] SVN: teeemcee/8845 Use gcc/clang builtin overflow-checking functions in array.c. Saves doin

[James Paige]

This revision breaks the build for me:

gcc -o build/array.o -c -O3 -DFBCVERSION=1050 -m32
-mpreferred-stack-boundary=2 -mno-sse -g -Wall --std=gnu99 array.c
array.c:107:26: error: #if with no expression
 #if has_overflow_builtins
                          ^
scons: *** [build/array.o] Error 1
scons: building terminated because of errors.

I am using gcc 4.8.4
