Compile error (unrecognized command line option '-assembler-with-cpp')

[gergalyb]

I strictly followed the instructions on this page: http://docs.megapirateng.com/documentation/compile But when I try to compile the code I get this error: avr-gcc: error: unrecognized command line option '-assembler-with-cpp'

I could narrow down this problem to that newer gcc uses this command instead: -x assembler-with-cpp

I was using 64bit win8.1. The compiling worked on OSX 10.9.5

Sorry, didn't realize there was already an issue exactly like this.
