Description franz.sirl-kernel 1999-10-08 12:59:28 EDT
The configure scripts of patch-2.5 detect the LFS support in
glibc-2.1, but due to the lack of a definition of
_GNU_SOURCE, no prototypes for fseeko are declared. That way
the compiler thinks fseeko is taking a 32bit argument for
the offset, when in reality it takes a 64bit offset.

Proof: compile with -W -Wall
Fix: modify the spec

Red Hat doesn't yet support LFS (because AFAIK it doesn't work on i386 yet).
I'm marking this problem deferred until we can deliver a working LFS on
all arches. Thanks for the patch.
