Bug#841923: AW: AW: Bug#841923: libclang-common-3.9-dev: missing multilib binaries

Tue Nov 1 15:18:57 UTC 2016

Hello,

Thanks for your patch. However, I don't really like the 
--ignore-missing-info option (especially as the doc says
"Usage of this option is discouraged")
Any other option?

Cheers,
Sylvesre
