I am building zeus with basic OpenCL support for centos 7.x, and using GNU 8.3.1 compiler and see the following Error when IGC is built, I see the same error when building with GNU 5.3.1...

Is this a known issue, is a patch available ?
Any ideas why I might be seeing this ?

cpp.o -MF IGC/Compiler/CMakeFiles/Compiler.dir/CISACodeGen/DebugInfo.cpp.o.d -o IGC/Compiler/CMakeFiles/Compiler.dir/CISACodeGen/DebugInfo.cpp.o -c /disk0/scratch/yocto_user/yocto/workspace_zeus/builds/sbcb-default/tmp/work/x86_64-linux/intel-graphics-compiler-native/1.0.11-r0/git/IGC/Compiler/CISACodeGen/DebugInfo.cpp

I am using bitbake -k, and everything else builds correctly, and no other components references this...

If I modify the header like so:

/usr/include/bits>diff stat.h stat.h_HOLD
106c106,108
<     __syscall_slong_t __unused[3];
---
>     __syscall_slong_t __unused1;
>     __syscall_slong_t __unused2;
>     __syscall_slong_t __unused3;
164c166,168
<     __syscall_slong_t __unused[3];
---
>     __syscall_slong_t __unused1;
>     __syscall_slong_t __unused2;
>     __syscall_slong_t __unused3;
08:29 smonsees@yix465383 /usr/include/bits>

IGC builds clean, and test show it appears to working correctly...

I really shouldn't be modifying the header, and would like to know what the real issue issue is...

Thanks,
Steve
