The code in question here runs many times in the normal course of any
Cygwin program -- debugger or no. The idea behind guarding the call to
OutputDebugString() with "if (being_debugged())" was that the call to
IsDebuggerPresent() was cheaper than the call to OutputDebugString(),
and that a well-behaived, non-debug build of a binary should not
needlessly send tons and tons of nonsense to OutputDebugString unless
it's actually being debugged and there is something there to interpret
the nonsense.
