[libvirt PATCH 1/6] meson: get rid of list of unused warning flags

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



We're not using these warning flags with libvirt, and it is not worth
keeping them just to issue a warning if someone tries to enable them.
If someone does try to enable them, either libvirt will build cleanly
or it won't.
