Original description

What change would like to see?

Include WProgram.h using a command line argument to avr-gcc instead of inserting it into the
source code of the user sketch.

Why?

To prevent pre-processing errors, like the one described at: <http://www.arduino.cc/cgi-
bin/yabb2/YaBB.pl?num=1261506776> (the #include ends up within a false #ifdef).

Would this cause any incompatibilities with previous versions? If so, how
can these be mitigated?

It would prevent people from using #defines to influence the behavior of the code in
WProgram.h, although it's not clear if anyone does this.

Including WProgram.h via command line doesn't solve the problem, another very similar issue but with a more complete test case is here: #2630
