How so?
Both Malcolm's example of nested structs (which, as it turns out,
*are* supported by SDCC) and my example of uppercase letters are
features that are required by all versions of the C standard.
You can either assume that all features required by the standard
are implemented, or not.
Though it does depend on what exactly we mean by "nested structures".
Structures as members of structures are supported by all conforming
C compilers. Anonymous structures are supported as an extension by
some pre-C11 compilers, and are a standard feature starting with C11.
If you have to use a compiler that doesn't fully conform to the C
standard, then of course you have to avoid the features it doesn't
(yet?) support. But in the absence of any such specific requirement,
it is in my opinion foolish to worry about it.
Not supporting lowercase letters is probably not a plausible
restriction. Perhaps long int would be a better example. I can easily
imagine a small embedded compiler not supporting long int; that's not
going to make me hesitate to use long int in my code if I need it.
