Suggestion for better compiler/OS support on linux/unix

As I was building your API into my application, I was having undefined reference errors on several methods that were in the RoboteqDevice.cpp file. Even though I was using the GNU compiler, linux was not defined. I would like to suggest changing all the lines like this:

To this:

Nearly all compilers support this for cross platform development. Alternatively, you can try chasing all the various forms of linux or __linux or __linux__ or even the upper case variants of those.

Also, in RoboteqDevice.cpp, eliminate compiler warnings and make the code slightly more readable by adding parenthesis around the bitwise operators in changing line 387 from:

To

The last compiler warning involves "i" as an unused variable on line 492 which can simply be removed.

We'll take this into consideration. Perhaps this will convince my team to start hosting this thing on github where you could just submit an issue.

Well, that would be nice. Between that and the other bug with the sleepms function that seemed to make it's way into 2.0, you'd be pretty well off :)
