 141   #
 142   # I had a file, say a1.c, that was included into liba.a.
 143   # I moved a1.c to a2.c, updated my Jamfiles and rebuilt.
 144   # My program was crashing with absurd errors.
 145   # After some debugging I traced it back to the fact that a1.o was *still*
 146   # in liba.a
 147   #
 148   # Rene Rivera:
 149   #
 150   # Originally removing the archive was done by splicing an RM
 151   # onto the archive action. That makes archives fail to build on NT
 152   # when they have many files because it will no longer execute the
 153   # action directly and blow the line length limit. Instead we
 154   # remove the file in a different action, just before the building
 155   # of the archive.
