Ah yes, C99 distinguishes initializers from expressions. The cast means that
the compiler interprets the assignment as non-constant. I think the default
mode (-std=gnu89) specifically allows this as a hack, mainly for Linux.
-std=gnu99 is likely to become standard option in future and it probably
wouldn't be hard to fix this.
