<pre>Starting with version 5, gcc will not warn anymore about incompatible pointer
types when converting a pointer to an array to a pointer to a const array. (The
underlying issue in the C standard is that the qualifier is attached to the
element type, so the usual rule which allows addition of a qualifier to a
pointer target does not apply). Please also consider this change for clang.
This would allow reasonable code such as the following to work without
warnings:
void foo(const double input[3][3]);
double b[3][3];
foo(b);</pre>
