Hi,
This test fails on a linux build because it tries to use the
LONG_LONG_{MAX/MIN} macros from "types.h". These are not guaranteed
to exist, and my system "types.h" doesn't provide them. C99 provides
LLONG_{MIN/MAX} for this purpose.
A gnu89 baremetal compiler doesn't seem to carry these macros
so we must add -std=c99.
But then this testcase doesn't properly declare its functions, relying
on an implicit int return type.
So I've fixed those up and now the test passes on aarch64-none-elf and
aarch64-none-linux-gnu.
I guess the patch is obvious and low risk as it is a target
specific test, but as we are late in Stage 4 I'd like
approval before I commit.
OK?
Thanks,
James
