Call me old-fashioned, but if it's an FFADO problem, the FFADO devel
list would have been the appropriate place to report.

If it's a gentoo problem, then well, some gentoo list.

Anyway, I've CC'ed ffado-devel. You probably need to subscribe:

libffado is C++, so --std=c99 is never correct. Please file a bug report
against your ebuild.

I might be mistaken, but are you compiling a 32bit library on a 64bit
system? Is that intended to be a cross-compile? I have no idea if
anybody has ever tried this. Should work in theory, but no guarantees.

On Debian, this compiles fine:

https://buildd.debian.org/status/fetch.php?pkg=libffado&arch=i386&ver=2.2.1-3&stamp=1448933457

while this doesn't mean there's nothing wrong with FFADO, I find it more
likely to be a Gentoo problem, especially due to lack of reports from
other distros.

Any chance to try this in a clean environment, for instance a Fedora
chroot?

And last not least: if you have a DICE device, you might not even need
FFADO anymore, provided you're running a recent kernel.

Cheers
