code to create a value of this type; this is only useful for passing
string values from Go to C and back to Go.

Using //export in a file places a restriction on the preamble:
since it is copied into two different C output files, it must not
contain any definitions, only declarations. If a file contains both
definitions and declarations, then the two output files will produce
