[Spice-devel] [PATCH 3/3] make allocation fixed instead of variable

[Frediano Ziglio]

Due to the way C handle constant variable the usage of these constant
were used as variable making compiler generate something like alloca
call while could compute allocation size statically.
Fix this using enum.
You can see the difference in the generated object file.
