I have compiled the trunk under your instructions with MSYS2/MinGW-w64
toolchain. The build process runs smoothly expect crash when compile
lisp/erc/erc-xdcc.el. Running emacs.exe with
-Q --eval '(byte-compile-file "Z:\\build-emacs/lisp/erc/erc-xdcc.el")'
under gdb I get the following backtrace. Is this information
sufficient or should I file a bug report?

I tried this in the 32-bit Windows build. (I don't have 64-bit tools
installed, so someone else will have to -- and should -- try that.)
It builds and passes the test suite, but hits assertion violation
during startup of a GUI session:

The -nw session does work.
This page:
http://www.peterstock.co.uk/games/mingw_sse/
seems to suggest it's a problem with our functions that are used as
callbacks: GCC aligns the stack to 16-byte alignment once at startup,
and assumes that this remains in effect for the duration of the
program. But when our function is called as a callback from a Windows
DLL, that alignment could be disrupted, since Windows itself doesn't
guarantee such a high alignment, it only specifies 4-byte alignment.
So, as suggested by that page, I marked the callback functions in
w32font.c with '__attribute__((force_align_arg_pointer))', and then
Emacs comes up normally. This attribute is available in GCC since
v4.2.
So the conclusion is that, at least for 32-bit Windows builds, the
alignment of union Aligned_Cons is not enough to produce the effect
you want, and additional measures are necessary.
I don't expect this to be a problem in 64-bit Windows builds, because
there Windows does enforce 16-byte alignment of the stack. But, as I
already said, I didn't test that.
This could be an issue in other x86 32-bit builds (probably not on
GNU/Linux, though, and not if GCC is the compiler), because AFAIK the
x86 ABI specifies a 4-byte stack alignment.
