ruby--ruby/ext/-test-/struct/len.c
normal 8e64799c96 fix RSTRUCT_LEN macro in public C API
rb_struct_size returns an Integer VALUE, so it must be converted
to a `long` for compatibility with previous Ruby C API versions.

* ext/-test-/struct/len.c: new
* test/-ext-/struct/test_len.rb: new
* include/ruby/ruby.h (RSTRUCT_LEN): use NUM2LONG
  [ruby-core:80692] [Bug #13439]
