>Description:
	

	The special handle arguments to dlsym, namely RTLD_DEFAULT, RTLD_NEXT
	and RTLD_SELF are not documented in dlfcn(3).  The absense of 
	RTLD_DEFAULT is particularly serious since this value implented the
	linux equivalent of searching the application itself.  Eg, the linux
	code:

	    root = dlopen (NULL, RTLD_GLOBAL | RTLD_LAZY);
	    lib = dlopen ("libm.so", RTLD_GLOBAL | RTLD_LAZY);
	    symbol = dlsym (root, "asin");

	has to be implemented as

	    lib = dlopen ("libm.so", RTLD_GLOBAL | RTLD_LAZY);
	    symbol = dlsym (RTLD_DEFAULT, "asin");
	
	on NetBSD.
