| 3 # link.sh -- try linking Vim with different sets of libraries, finding the | |
| 4 # minimal set for fastest startup. The problem is that configure adds a few | |
| 5 # libraries when they exist, but this doesn't mean they are needed for Vim. | |

| 32 # There is a loop to remove libraries that appear several times. | |
| 33 # | |
| 34 # Notes: | |
| 35 # - Can't remove Xext; It links fine but will give an error when running gvim | |
| 36 # with Motif. | |
| 37 # - Don't remove the last -lm: On HP-UX Vim links OK but crashes when the GTK | |
| 38 # GUI is started, because the "floor" symbol could not be resolved. | |
