After some lightweight preprocessing, it's C code.

It uses the so-called "designated initializer" syntax of C:
  (struct_type){.member=value}
See https://gcc.gnu.org/onlinedocs/gcc/Designated-Inits.html
and ISO C11 section 6.7.9.

This macro S_help_ relies on how the symbol_tab gets initialized (in spvw.d).
