Control when to treat a trailing array as a flexible array member. Mirrors the -fstrict-flex-arrays=<n> compiler flag.
pub const StrictFlexArraysLevel = enum
pub const StrictFlexArraysLevel = enum {
/// Any trailing array member is a flexible array.
@"0",
/// Trailing arrays of size 0, 1, or undefined are flexible.
@"1",
/// Trailing arrays of size 0 or undefined are flexible (default).
@"2",
/// Only trailing arrays of undefined size are flexible.
@"3",
