The author recommends -std=c99 (-pedantic) default flags, yet suggests K&R (2nd edition, presumably) as a reference...

Also, why still use the old confusing long, short, long long etc... types when the much better fixed-width types had been standardized in stdint.h since C99 (even the Visual Studio C compiler has those since at least VS2015).

Little reason to not use at least -std=c11 these days

Linux is C99, most microcontrollers use C99 or even C89. It would be nice to get the new features, but it's not always possible.

Most microcontrollers are ARM Cortex-M and are programmed with a recent GCC toolchain

MSVC has C11 support only since very, very recently:

https://devblogs.microsoft.com/cppblog/c11-and-c17-standard-...

(it has a solid subset of C99 since around VS2015 though, just _Generic was missing - and ignoring VLAs, which have been "dropped" in later C standards anyway).

Verifiers haven't caught up to C11 yet.
