Comment:

 Replying to [comment:15 jacek]:
 > D3DCOMPILER_DLL define is fixed in upstream mingw-w64 now. I recall that
 some declarations also vary between d3dcompiler versions, so if similar
 problems persist, it might be good place to look.

 Thanks! It seems we are fine for now by just bumping the mingw-w64 commit
 we use (see the test results in comment:32:ticket:28823 compared to
 comment:28:ticket:28823). `bug_28874`
 (https://gitweb.torproject.org/user/gk/tor-browser-
 build.git/commit/?h=bug_28874&id=5e875c30e825bd726558a3b9fea63b59d2a80d15)
 has the respective patch for review.
