Hello,

Could you, please, let me know if I need to provide some additional
information for this? I thought the patch was straight forward, but I may be
wrong.

Thank you,

Hello,

This patch fixes PR 2343: when host and target system OS differ, there can
be mismatch between signal numeric values. This patch introduces new gdbarch
function to allow different targets define their own mapping to enum
target_signal.
