Comment (by ballapete):

 The original patch has a flaw: the path component ``luametatex-2.10.08/``
 needs to be removed. With this change it applies – but a new failure
 rises:

 `luametatex-2.10.08/source/tex/textypes.h` has:

 {{{
    82   typedef int             strnumber;
    83   typedef int             halfword;
    84   typedef long long       fullword;
    85   typedef unsigned short  quarterword;   /*tex It really is an
 unsigned one! But \MPLIB| had it signed. */
    86   typedef unsigned char   singleword;
    87   typedef int             scaled;
    88   typedef double          glueratio;     /*tex This looks better in
 our (tex specific) syntax highlighting. */
    89   typedef int             pointer;       /*tex Maybe I'll replace
 halfwords that act as pointer some day. */
    90   typedef FILE           *dumpstream;
 }}}

 and later `luametatex-2.10.08/source/utilities/auxposit.h` is included
 providing these:

 {{{
    93   typedef int       halfword;
    94   typedef posit32_t tex_posit;
 }}}

 I'll check whether line #93 can be deleted.
