libzigc: stropts/isastream
`isastream` is an old, deprecated function for the STREAMS framework.
Linux doesn't even support this natively, and so the musl implementation
just returns 0 (not a STREAMS file) for valid file descriptors or -1
(for bad file descriptors).4 files changed, 18 insertions(+), 8 deletions(-)
