Re: Two questions on arrays with size defined by variables

I haven't checked what's actually valid in current or former
"C" compilers or standards. As it's of minor relevance (to me)
I just see whether the compiler accepts my main() declaration
or not. (There was never a problem here, so why should I care.)

That was probably meant to be a rhetorical question, but ...

Because it might not always work in the future, when you port your
code to another system, when a new release of the compiler you're
using is installed, or during the next full moon.  If your code
has undefined behavior, it might appear to work perfectly until
it doesn't.

If your code is valid according to the C standard, you're less likely to
run into problems -- and if a compiler rejects your code you have a good
basis for a bug report.  If "void main()" or "main()" starts behaving
differently, or being rejected, you don't have much recourse.
