• OpenOffice.org 1.1.x installer broke on large disks (Issue 26865)

• easy fix (build with -DLARGEFILE_SOURCE -D_FILE_OFFSET_BITS=64)

• would have been a good fix for 2.0.0..

• • didn't happen, reluctant to make this only in my build
  • still not resolved
  • kr thinks it won't even change external ABI

• can we fix it? (Even if not determined to be needed it makes sense to have it)
