Other examples, even the most trivial blink, fails to compile with the same error.

Shifting the arm-none-eabi-gcc tool-chain from 6.3.1-20170620 to 4.8.4-20140725 solves the issue.

The 6.3.1-20170620 version already packs the utoa() and itoa() functions in stdlib.h, contrary to the 4.8.4-20140725 version, hence the conflict with itoa.h.
