af220472c9 Ensure that the struct atexit_handler has been removed from the list 
of pending atexit handlers before the structure is reused.  This prevents
__cxa_finalize from going into an infinite loop when an atexit handler
register a new atexit handler as in:

   #include <stdlib.h>

   void two(void) {
   }

   void one(void) {
           atexit(two);

15b661abe9 Fix several end cases: 
o If a long option looks like an ambiguous abbreviation of two or more long
  options, but all the possible interpretations would return the same
  value, then just return that value without complaining that it's
  ambiguous.

o If a long option could be interpreted either as an exact match for one
  long option, or as an abbreviation for one or more other long options,
  then treat it as the exact match.

These changes align NetBSD's getopt_long(3) with the current behavior of
GNU getopt_long(3), the de facto standard, and FreeBSD's getopt_long(3).

7a2af2aba0 Rewrite erand48() to put the random bits into the mantissa by simple 
bitshifts instead of calling ldexp() three times.
(for ieee doubles only -- vax can't use it, so the old version
needs to stay around)
This removes the dependency on ldexp() which also didn't participate in
the usual __RENAME game, thus lead to confusion.
In addition, this version is almost 3 times as fast for me.
