I had this at one point today, as well, when I had installed
libunistring into /opt/foo/ but had my libdir wrong (/opt/foo/lib vs
/opt/foo/lib64)...

Crazy to get an error about sizeof(float). I wish unistring added its
info to UNISTRING_CFLAGS/UNISTRING_LIBS like other libraries instead of
CFLAGS so it would affect checks like this.

While we're complaining about the build :-) It seems we require gperf
now. Is that correct? Can that build-dependency be removed somehow? It
seems to be a build-time dependency, though it could be only for
maintainers.

If in fact it is only for maintainers, perhaps we should keep the
generated whatevers in git. I just had to ask the build folks at work to
add unistring as a dep, and I'm a little concerned about asking for
gperf too :P

I think that's how my error panned out too, but for you it should work.
Maybe we should get Bruno involved, if Ludovic doesn't know anything...

On my laptop, yes, in anticipation of someone packaging it up. Grr
unpackaged dependencies!!
