Comment:

 That's good news! Now, how should the patch look like, Mike? We have,
 roughly speaking, three options:

 1) Just take my precompiled mingw runtime libs and adjust the Windows
 gitian-firefox.yml accordingly.

 2) Include the modification and compilation of the mingw runtime libs into
 the Gitian system and modify gitian-firefox.yml accordingly (we could use
 then our own compiled mingw to compile everything although this is
 orthogonal to this bug).

 3) Go for the second way outlined in comment 35: write the proper mingw
 patches and avoid the mess with linking against msvcr100 and above all the
 additional binary blob we deliver (msvcr100.dll).

 (Note: Apart from that there are still some rough edges to fix in my
 current setup: the nss libs are not linked against msvcr100 yet (for some
 unknown reason); I need to apply a small patch deep down in Mozilla code
 (nspr) do avoid the _strcmpi issue in comment 25 which is in fact a mingw
 issue I am still investigating)
