These functions are only available in the preamble, not in other C
files. The C code must not modify the contents of the pointer returned
by _GoStringPtr. Note that the string contents may not have a trailing
NUL byte.

As Go doesn't have support for C's union type in the general case,
C's union types are represented as a Go byte array with the same length.

Go structs cannot embed fields with C types.
