I see. From what I can understand, APR is using off_t (or a typedef of
it) in its API (that is, in a public header file as opposed to a source
file). In which case switching from a 32-bit to a 64-bit off_t would
indeed break binary compatibility.

If so, it's too late to change anything now, but I wonder why APR RPM
packages wwere built with a 32-bit off_t in the first place. On Linux
most software is built with _FILE_OFFSET_BITS=64 defined these days.
This is not a "fix".

OK, but with _FILE_OFFSET_BITS=64 or a similar macro defined, all recent
Unix and Linux platforms actually have a 64-bit off_t. And most software
is compiled with _FILE_OFFSET_BITS=64 defined these days. Linux and Unix
platforms are not really platforms with a 32-bit off_t.

If I understand correctly, APR could actually support large files, but
enabling large file support would break binary compatibility in APR, so
it's kept disabled for now, probably until the next major version number
leap.
