| 132 | | # |
| 133 | | # I had a file, say a1.c, that was included into liba.a. |
| 134 | | # I moved a1.c to a2.c, updated my Jamfiles and rebuilt. |
| 135 | | # My program was crashing with absurd errors. |
| 136 | | # After some debugging I traced it back to the fact that a1.o was *still* |
| 137 | | # in liba.a |

| 139 | | # Rene Rivera: |
| 140 | | # |
| 141 | | # Originally removing the archive was done by splicing an RM |
| 142 | | # onto the archive action. That makes archives fail to build on NT |
| 143 | | # when they have many files because it will no longer execute the |
| 144 | | # action directly and blow the line length limit. Instead we |
| 145 | | # remove the file in a different action, just before the building |
| 146 | | # of the archive. |
