[mosh-devel] [PATCH] Make errors from setsockopt( IP_MTU_DISCOVERY ) non-fatal.

[Daniel Thompson]

Currently any failure to set this option cause a fatal exception to be
thrown. This is odd because the code itself is conditionally compiled.
Fixing this the "obvious" way by showing a warning gets mosh confused
about the terminal state so we copy the same commented-out-perror
approach used a few lines later.
