linking shared libs with -lc considered harmful

[Please correct if that's completely bogus]

gcc-2.7 doesn't include -lc when linking shared libraries, egcs
does. If you don't add -lc on the command line:

gcc -shared		-> ld -lgcc -lgcc
egcc -shared		-> ld -lgcc -lc -lgcc

Adding -lc ...

gcc -shared -lc		-> ld -lc -lgcc -lgcc
egcc -shared -lc	-> ld -lc -lgcc -lc -lgcc

IMHO this is worse than linking without -lc, because libc is searched
before the internal libgcc. That's the cause of our
__register_frame_info problems. It was found in libc, not in libgcc.

What to do?

- Fix the gcc specs such that -lc is used when building a shared
  library (should be done for slink, such that shared libs on slink
  can be built without explicitely linking libc).

- As an interim solution, link shared libraries with -lgcc -lc
	gcc -shared -lgcc -lc	-> ld -lgcc -lc -lgcc -lgcc
	egcc -shared -lgcc -lc	-> ld -lgcc -lc -lgcc -lc -lgcc

- Another interim solution (not sure if that's right): change specs,
  such when linking shared libs, each -lc is replaced with -lgcc -lc -lgcc

- As a final solution, don't link shared libs with -lc

Could linitan detect if a shared lib is linked first with -lgcc -lc or 
simply with -lc?
