Hallo,

Unfortunately i have got several bug reports where people complaints
crashes
of blender-2.49b because they have files with more then 2G on there disc.

this crashes are occures because off_t has a size of 4 bytes on a
32-bit system if
you con't explicit request large file support during compile time.

So I want to notfy you about this issue, so you can file Blender-2.49b
and the
upcoming 2.50 release if necessary.

Best Regards:

Jochen Schmitt
