>Description:
If an array is declared at file level with a size given by a named constant (declared as 'const int x = 5' for example), the compiler incorrectly rejects it with the message "variable-size type declared outside of any function". This conflicts with A8.6.2 from K&R2.
>How-To-Repeat:
const int x = 1;
int y[x];

gcc -c demo.c
>Fix:
Don't do this.
