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

src/solaris/npt/npt_md.h
src/solaris/native/sun/awt/fontpath.c
src/solaris/native/sun/java2d/opengl/OGLFuncs_md.h
src/solaris/native/sun/java2d/x11/XRBackendNative.c
src/solaris/native/sun/security/pkcs11/j2secmod_md.c
src/solaris/native/sun/security/pkcs11/wrapper/p11_md.c
src/solaris/native/sun/security/jgss/wrapper/NativeFunc.c
src/solaris/native/sun/security/smartcardio/pcsc_md.c
src/solaris/native/sun/nio/fs/GnomeFileTypeDetector.c

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.
