Build error

[whoenig]

Building the latest master version breaks the build using arm-none-eabi-gcc 6.3.1 20170620 on Ubuntu 16.04:

src/utils/src/eprintf.c: In function 'evprintf':
src/utils/src/eprintf.c:232:11: error: this 'if' clause does not guard... [-Werror=misleading-indentation]
           if (isdigit((unsigned)*fmt))
           ^~
src/utils/src/eprintf.c:234:13: note: ...this statement, but the latter is misleadingly indented as if it is guarded by the 'if'
             fmt++;
             ^~~

This code was changed/introduced about 5 days ago, see https://github.com/bitcraze/crazyflie-firmware/blame/master/src/utils/src/eprintf.c#L232-L234.

Also, what compiler version is the travis cl using? It should have caught the problem.

Hi,
This has been fixed this morning in 26a78f8 and we are updating the docker builder (used in travis) to use the latest arm-none-eabi. Currently travis is using 2016Q2 and this error is found by 2017Q4. It seems that GCC got much better at static analysis lately.
