>             Project: Hadoop YARN

> I just checked changes of this JIRA doesn't relate to issues I saw, I tried to revert this patch but issue is still the same.
> It seems the set (CMAKE_C_STANDARD) doesn't work for the nodemanager project. 
> I hardcoded to change set (CMAKE_C_STANDARD 99) to set (CMAKE_C_STANDARD 90) in nodemanager project. (Since we have code uses C99-only syntax, so changing to 90 should fail build).
> I tried on two different environment:
> 1) Centos 6, cmake version 3.1.0, gcc 4.4.7
> For both 99/90 standard, all fail.
> 2) OSX v10.12.4, cmake version 3.5.2, cc = "Apple LLVM version 8.1.0 (clang-802.0.42)". 
> For both 99/90 standard, all succeeded.
> At least for the for loop in gpu-module.c is C99 only:
> {code}
> for (int i = 0; i < n_minor_devices_to_block; i++) {
>    // ...
> }
> {code}
