This is a C99 feature: a structure that ends with a member of type
"array of T" (for some valid data type T), with no size, creates
a struct type with a "flexible array member". While C99-conformant
compilers are becoming more common, in my opinion they are not yet
common enough to recommend regular use of C99 features. Still,
this is a reasonable thing to do if you have C99 compilers. This
gives:

Just an FYI (for others, since Chris is probably familiar), this technique
existed prior to C99. It was called the C90 'struct hack' and works with
almost all C compilers. When standardized in C99, it became known as
variable length arrays.

If you've never heard of the C90 'struct hack', read #28 here:
