Possibly dumb signal mapping question

[Kris Warkentin <kewarken at qnx dot com>]

Say I'm building a gdb on Linux that remotely targets Neutrino, what is 
the acceptable way to map our OS signals onto TARGET_SIGNAL_*?  I'm 
looking at the target_signal_[to/from]_host functions but they look like 
they depend on the various SIG*s having been defined.  Wouldn't those 
defines collide with host defines?  Perhaps I'm getting confused for no 
good reason....  If I _were_ going to define them, what would be a good 
place?

I accidentally dropped the signal mapping code from our old port but in 
looking at it, it looks too hacky to live.  We've got some ugly 
target_signal_[to/from]_qnx functions that we just use to convert any 
signals sent to and from the remote target.  Is there a better way?

cheers,

Kris
