This appears to be a problem with g++ on AIX, caused by AIX having
"#define open open64" in one of its headers:


It might be possible to work around this with e.g.:

	#include <fcntl.h>
	#undef open

But you'd need to figure out which file(s) require it, maybe with:

	nm -A OBJ.*/*.o | c++filt | fgrep open64

[This would work on Linux, but I don't know about AIX.]
