Sorry, but you don't seem to understand, what a standard is. Do you also say
"never buy A4 paper, because every manufacturer has it's own A4 paper size, so
it may not fit in your printer"? Why do you trust the ISO A4 standard but
doubt the ISO C standard? And no, there is no C standard other than ISO/IEC
9899:1999 (E), especially not several "not-exactly-compatible".

I don't know if any compiler that outputs a warning message in this case. And
your advice is NOT good. Portable programs are programs that don't make
assumptions about anything not defined in the standard. But they MUST trust
the standard, because if they don't, all bets are off. If you write your code
according to the standard, and it fails, it is because the compiler is broken.
If you write your code with just your beliefs, your code may or may not work,
but you'll never know for sure.
