Smallest Compiled Program

Today's challenge will require you to use a compiled language (ie not javascript, python, or ruby). The goal is to create the smallest program in that language that will compile and print out "Hello ProblemOTD".

    In Scala, we can write: 

    object HelloPOTD extends App {
  println("Hello ProblemOTD")
}

    This can be compiled: scalac HelloPOTD.scala ... and then run: scala HelloPOTD.

    Just in case it's not "cheating", we can get away with less if we write a Scala script:

    println("Hello ProblemOTD")

    This can be compiled and run: scala HelloPOTDScript.scala

    Both scenarios produce the prescribed output.

    C

    main(){puts("Hello ProblemOTD");}

    Compile with

    gcc hello.c

    It gives a whole bunch of warnings, but #includes for standard functions, function type declarations and return statements are technically optional in C (at least the dialect that gcc understands)!

    FWIW, I'm sure there's a whole bunch of dirty black magic obfuscation tricks that could compress this even further. I'm not that ambitious.

    Since you highlight use of a compiled language, do you intend for the "smallest program" to refer to byte size of the compiled program or the character length of the code?
