Currently, apr chooses whether to use epoll, kqueue, port, select or
poll at build-time. This works quite well if your apr library is only
used on hosts with the same capabilities as the one you built on.
However, if you build on Linux 2.6 and try to use the binaries on
Linux 2.4, they don't work (due to the epoll interface not existing on
2.4).
Of course, so don't do that. If your lowest supported kernel revision
is 2.4, then you have to build on a 2.4 kernel so APR won't use any 2.6
features. Otherwise you have to force particular choices by doing e.g.
"export apr_cv_epoll=no" before running configure, to prevent detection
of 2.6 features.
Wouldn't it be better if APR chose at runtime instead of just
segfaulting like it does today?
