In sectino 6.5.7.2 of the Standard, I believe it states that variable length arrays (VLAs) are supported as long as they are not in file-scope.
But maybe someone can check out Example 4 and give me a better explanation. I don't think its perfectly clear where and what I am allowed to do. Let alone what tcc is striving to do... Thanks.
