ADDITIONAL OS VERSION INFORMATION :
Linux 3.0, IBM AIX 7.1
A DESCRIPTION OF THE PROBLEM :
link.h is included in following source files from OpenJDK codebase
But link.h is not part of POSIX standard, see http://en.wikipedia.org/wiki/C_POSIX_library, moreover this including causes portability problem for other Unix-like platforms, such as AIX. So far as I see, OpenJDK only uses POSIX.1-2001 compatible dlopen, dlclose, dlsym, dlerror functions, no special extensions involved, so here suggest to remove link.h and use dlfcn.h only.
This bug can be reproduced always.
