Sdk: dart2native under Linux produces *.exe files

[pycebs]

I was really looking forward to dart2native and so I experimented with it a little bit today. I use Linux and when I run dart2native, the resulting binary is an *.exe file. I know I can just change the name of the binary with the -o flag, but producing *.exe files on Linux is still a pretty weird standard behaviour.

Just wanted to report the same thing, looks like code attempts to name it correctly but fails somewhere:

I tried to strip the resultant binary on linux and running it now gives the dart usage info, and does not run the program at all.

Yes, it shows the same on mine. In all circumstances before this strip will refuse to run a file that already has been. On these dart binaries, it doesn't seem to recognize they are and will break them.
