--> Why does it say hb_.language_t and not hb_language_t ?? Is that by purpose?
Maybe the first part is taken as some kind of class name. But why isn't then the underscore replaced?

3 home daniel .cache jhbuild build harfbuzz src HarfBuzz-0.0.gir

...
    <constant name="LANGUAGE_INVALID" value="0" c:type="HB_LANGUAGE_INVALID">
      <source-position filename="jhbuild/checkout/harfbuzz/src/hb-common.h"

      <type name="language_t" c:type="hb_language_t"/>
    </constant>
...

--> a reference to hb-common.h

4 home daniel jhbuild checkout harfbuzz src hb-common.h

/* hb_language_t */

typedef const struct hb_language_impl_t *hb_language_t;

HB_EXTERN hb_language_t

...

  --> a git blame around these lines said the last change was in 2017, so probably not related to this error

5 hb-comon.cc

--> the original error was 
  HarfBuzz-0.0.gir:239.5-239.79: error: `hb_.language_t' not supported as type for constants
Maybe the type hb_language_impl_t has changed? -> No change since 2012

/* hb_language_t */

struct hb_language_impl_t {
  const char s[1];
};

Was this ever solved?
