8e0a22a5fb "weak symbol" support (fudged into `a.out' by means of the n_other field). 
Weak symbols are to replace indirect (type N_INDR) symbols and will help
to clean up name spaces in libraries.

Also, some misc. bug fixes, including PR 586, and use stdio for the output
file entirely.

a6bf4f8176 Conversion to err()/warn() for error reports. 
Minor bug fixes:
	a case of free()ing in the wrong order. (from Rick Murphey).
	processing alias symbol twice (sometimes).
Some miscellaneous cleanup.

72b85788e5 function parse() has moved to ld.c, thus avoiding scanf() code to be 
included in ld.so.

12f28a9ba6 PC relative segment relocations don't need to be looked at at run-time (such 
relocations occur on the ns32k).

90cfba21cb Use `.type' directives generated by gcc. 
Numerous internal changes & bug fixes.
NOTE: must re-compile & re-link shared libraries before used to link programs.

fa099af1f6 Many internal changes, most notably in the symbol counting stuff. 
`ld -r -x'  now supported on all object files.
Support for long archive member names (AR_EFMT1 format),
	thanks to Bill Sommerfeld/Mark Eichin
Do the right(?) thing with symbol aliases (N_INDR) for POSIX lover, especially
when equiping shared libraries with these (this was *not* fun).
Handle silly archives (.sa) for people who needs them; turn on by `-Bsilly'.

e5b3eedefb Eleminate duplicate inclusion of shared objects (libgcc!). 
Start using auxiliary information (using `n_other') to tackle aliasing of
function addresses and direct function calls in shared objects.
