So that's strange. When I run make_opengl extension_registry_size grows 
to 2695 and Wine does not compile because gl.xml now depends on 
khronos_*_t types that we don't have in Wine:

In file included from ../d3dx9_36/txc_dxtn.h:29,
                 from ../d3dx9_36/surface.c:28:
../../include/wine/wgl.h:14:9: error: unknown type name ‘khronos_int8_t’
 typedef khronos_int8_t GLbyte;
         ^~~~~~~~~~~~~~

This seems to come from:

diff --git a/include/wine/wgl.h b/include/wine/wgl.h

And from gl.xml before that:

        <type name="khrplatform">#include <KHR/khrplatform.h></type>
[...]
        <type requires="khrplatform">typedef khronos_int8_t <name>GLbyte</name>;</type>

        <type requires="khrplatform">typedef khronos_uint16_t <name>GLushort</name>;</type>

The khronos_*_t types seem to have been introduced back in mid 2018 in 
the 1e2f5a0d commit.

Is there a trick to running make_opengl?

I see three options:

* Tweak the wget URLs to retrieve older versions of gl.xml and wgl.xml. 
  Which would likely freeze the extension registry to about 2680.

* Add the khronos_*_t types to Wine (but I don't see them in the 
  Windows headers).

* Tweak make_opengl to remove the khronos_*_t references when generating 
  the source files.
