AIX 7.2 Failed to build psutil - "incomplete type 'struct procinfo'" when running gcc

Platform

• OS: AIX 7.2
• Python version: 3.6.6
• psutil version: 5.6.3
• gcc version: 7.2.0
• wheel version (installed in venv): 0.29.0

Bug description Newest release of Psutil - 5.6.3 - doesn’t compile on AIX 7.2. Version 5.6.2 was building properly.

That’s strange. I can’t reproduce this behavior. The only thing that may be relevant that changed from 5.6.2 to 5.6.3 in AIX is the order of the include files, but I don’t think it matters. Can you please try to compile a test file?

#include <procinfo.h>
void main(void)
{
	struct procinfo test;
}

Put it in test.c and run gcc test.c. Please let us know if it compiles successfully.
