Maybe now it does not work on Ruby 2.6. This file must be changed for
each Ruby version. I have no good idea to fix this issue.
As d387029f39 made io/wait
unbuildable with older versions, drop older versions tentatively.
Also the change seems to instroduce behavioral incompatibilities,
may address them or bump up the version later.
Onigumo 6 (r57045) introduced new onigumo.h header file, which is
required from quite much everywhere. This commit adds necessary
dependencies.
Note: ruby/oniguruma.h now includes onigumo.h,
ruby/io.h includes oniguruma.h,
ruby/encoding.h also includes oniguruma.h,
and internal.h includes encoding.h.

arguments may change in the future. [Feature #12013]

first and check FIONREAD optionally to see if EOF.

* ext/io/wait/wait.c (io_wait_writable): this is easier to use than
IO.select for a single IO object and is immune to the
limitations/innefficiency of select() on platforms where poll/ppoll
is available. patched by Eric Wong. [Feature #4646]
