I concur. On the other hand, which platforms are affected by this
problem?  Any platform maintainers care to comment?  Maybe we can
drop the code :)

A side note: we'd be better off reimplementing pipe_open (and similar
functions) individually on a per-platform basis to avoid the ugly
CPP conditionals.

Right now, it's hard-to-read for every platform.  Of course, this split
requires much coordination between platform maintainers...
