static qualifier in array parameter declaration

[monniaux]

C99 §6.7.5.3-7 states that static in an array parameter declaration means

If the keyword static also appears within the [ and ] of the
array type derivation, then for each call to the function, the value of the corresponding
actual argument shall provide access to the first element of an array with at least as many
elements as specified by the size expression.

Thus the following should be accepted:

int foo5(int t[static 1]) {
  return t[0];
}

int foo6(int t[const static 1]) {
  return t[0];
}

I suspect the simplest is to ignore this keyword. (Technically, one could use it to convey semantic information that the area pointed to should be accessible for a certain length, thus allowing some optimizations such as speculatively loading values, but this would require quite a bit of work…)
