[rock-devel] [PATCH] large file support (LFS) for fl_wrapper

[Rene Rebe]

Hi all,

to finalize our T2 OpenOffice package, I had to fix the fl_wrapper to be 
able to write logs exceeding 2GB on 32bit architectures such as x86 and 
PowerPC.

I though you might be interested as well - so I rediffed it for ROCK 
Linux trunk:HEAD.

PS: Please do not forget to regenerate your fl_wrapper.c from the .sh.

Yours,

PPS: I'm still not on the list - thus please CC me on reply.

Added large file support to the flist wrapper. Rediffed for ROCK Linux HEAD.
