DevOps, CI/CD and Automation

On my openSUSE 11.2, I can't compile very simple C++ source files, for example the Welcome sample. The root of evil I believe is #include <iostream>.
I receive the following error message:
"/usr/include/stdio.h", line 482: Error: "(" expected instead of "_attribute_".
"/usr/include/stdio.h", line 482: Error: "(" expected instead of "_attribute_".
"/usr/include/stdio.h", line 482: Error: ")" expected instead of "_attribute_".

"/usr/include/stdio.h", line 490: Error: ")" expected instead of "_attribute_".
12 Error(s) detected.

Yesterday I finally figured out a very likely solution:
replace /opt/sun/sunstudio12.1/prod/include/cc/sys/cdefs.h
with the sun studio 12 supplied one.

These two files are listed here:

cdefs.h defines __attribute_ macro to disable attributes support
for compilers which don't define GNUC. We don't define GNUC
but want attributes support, hence the interposed header.

#undef attribute

The differences are located at here:
#ifndef _cplusplus
#undef __attribute_
#endif

I'm wondering if this modification to cdefs.h is harmful.

Best Regards.
