Indeed, every C compiler including gcc is slightly different. Especially in the embedded space where pseudo-standards become a small subset of GNU compatible code very quickly. To be honest, gcc became the unofficial standard even with the GNU extensions.
Good C follows the 10 rules, uses old compatible macro language features, and is boring to trivially port. The "hold my beer" folks often go back to Python where the abstractions hide the foot-guns.
