That sounds right, but I haven't looked too deeply as I don't have a win64 
system either and I don't want to delay the 3.15.0.1 release any longer.

It would probably be feasible to debug this using the MinGW cross-compiler on 
Linux, which I have successfully used to cross-build 32-bit executables (they 
cross-compile *much* faster than building on Windows) — the MinGW cross-tools 
are packaged on both Ubuntu and Fedora/RHEL.  Add a CROSS_COMPILER_TARGET_ARCH 
setting and edit the recently-added CONFIG_SITE.linux-x86.win32-x86-mingw file 
to set GNU_TARGET and GNU_DIR as necessary.  For 64-bit you'll need to add a 
CONFIG.linux-x86.windows-x64-mingw file which can probably just include its 
32-bit counterpart and override one or two variables to add -m64 to the 
compile and link lines.

I don't have Janet's errors and she's gone home now.  As I said above I don't 
think this should hold up the release, which I might even be able to make 
tomorrow after some last-minute commits and merging bug-fixes from 3.14.
