Problem Description:

	ld.so 1.66 contains fixes for these bugs:
	
	1033086: Calling dlopen() on a file with BSS kills your application.
        1043300: dlclose prevents access to functions even after further dlopen
        1046379: cannot call a function in a [.so] from a function in another
        1052428: ld.so usage of -L options confusing, leads to security probs
        1045194: dlsym returns bad address for uninitialized global variable
        1069404: bad handle errors with dlopen(NULL...)
        1070559: SPARC ld.so's are not architecture independent
	1076903: cascaded dependency checking too restrictive
	1083431: dlsym() can fail to find all symbols
	1071781: fix "relocate()" to deal with "interpreted" symbols properly.
 
        ldd 1.6 contains fixes for these bugs:
 
        1032208: ldd doesn't write file names if standard output is not a tty
        1032209: ldd runs out of file descriptors
 
        And, ldconfig 1.10 contains fixes for this bug:
 
        1043082: Bogus first arg to 'ldconfig' kills dynamic linking


	For brevity, and because this patch relates exclusively to ld
	and its support programs, this patch contains fixes to 3 ld
	"parts"; ld.so (the dynamic linker), ldd (dynamic dependencies
	lister), and ldconfig (dynamic path cache tool).

	Unpacking this one patch will provide binary executables for
	ld.so, ldd, and ldconfig.  The result will be a hierarchy that
	contains both SPARC and M68K versions of the referenced
	programs.

	The installation instructions below will address, seperately,
	the install sequence for each of the 3 patches.


INSTALL:

   As root install the following patches:

   For ldd:

	mv /bin/ldd /bin/ldd.FCS
	cp -p {4.1.1, 4.1.2, 4.1.3, 4.1.3c}/`arch`/ldd /bin/ldd
	chmod 755 /bin/ldd

   For ldconfig:

	mv /usr/etc/ldconfig /usr/etc/ldconfig.FCS
	cp -p {4.1.1, 4.1.2, 4.1.3, 4.1.3c}/`arch`/ldconfig /usr/etc
	chmod 755 /usr/etc/ldconfig

   For ld.so:

	cp -p {4.1.1, 4.1.2, 4.1.3, 4.1.3c}/`arch`/ld.so /usr/lib/ld.so+
	chmod 555 /usr/lib/ld.so+
	mv /usr/lib/ld.so /usr/lib/ld.so-; mv /usr/lib/ld.so+ /usr/lib/ld.so
	date

If the "date" command does not run correctly, then IMMEDIATELY put back
the old ld.so:

	mv /usr/lib/ld.so- /usr/lib/ld.so

NEVER "cp" or otherwise copy over an installed ld.so.
