--block-outside-dns only works on Windows.

Yes thank you,
Would be fine if openvpn could warn on linux if there is a windows configuration.
I wasted time to find out what's going wrong, comparing Linux and Windows configuration.
It is the same to find the error when writing 1+1=3, you are searching on every line of the code but not at this line :-(
So if Linux would warn: "configuration mismatch: --block-outside-dns not allowed on Linux" would be very helpful
