Bootstrap failure on master with native compilation for Windows

[Andy Moreton]

Hi,

Building from latest master branch on Windows using the mingw64
toolchain works if native compilation is disabled.

With native compilation enabled, there is an error in a bootstrap build
from a clean tree when dumping:

    GEN      autoloads

  C:/emacs/git/emacs/master/src/lread.c:5485: Emacs fatal error: assertion 
failed: NILP (Vcomp_abi_hash)

Running a git bisect points to commit edf37e811caf ("Implement drawing
text with DirectWrite on MS-Windows.").

Possibly something to do with defsubr calls in syms_of_w32dwrite, and the
latter being called in the wrong initialisation order ?
