No more than it already breaks them, since they don't know what
-shared is either, to most linkers, its -s hared, setting the
start symbol to 'hared'. And yes, I will create a changelog, sorry I
didn't include one in the mail.

How about this:

	* configure.in: check to see if we're using GNU ld, and set
      gcc_cv_ld_is_gny to yes if we are; search for as and ld in
      /usr/ccs/bin/elf before /usr/ccs/bin; remove dependency on
      GNU grep by using sed addressed, and cleanup up the check for
      mixed RO/RW sections.
      * tlink.c (recompile_files): fixed putenv() arguments.
