• Describe the scope of your change--i.e. what the change does and what parts
  of the code were modified. This will help us understand any risks of integrating
  the code.

This change modifies Adafruit_BMP085_U.cpp to eliminate two unused variables that would appear as red warnings during compiles using the unmodified code.

• Describe any known limitations with your change.

None known.

• Please run any tests or examples that can exercise your modified code. We
  strive to not break users of the code and running tests/examples helps with this
  process.

It compiles without the warnings for me.
