Just a few comments..
I do MSYS2-MinGW64 Emacs trunk builds with the simple steps:
./autogen.sh
./configure --prefix=/Emacs.app --with-wide-int
--build=x86_64-w64-mingw32 --without-imagemagick
'CFLAGS=-I/mingw64/include/noX -Ofast -g0 -pipe' LDFLAGS=-pipe
make...
The build needs the
CFLAGS=-I/mingw64/include/noX
definition because of the manner how MSYS2 work. It puts all the stuffs
depending on msys2*dll (the equivalent of cygwin1.dll) under /usr.
Instead the MinGW34 and MinGW64 applications are under /mingw32 and
/mingw64 respectively. Usually, to work with MinGW64 applications, one
needs to start the shell-console with mingw64_shell.bat batch file
(msys2_shell.bat or mingw32_shell.bat to work with MSYS2 or MinGW32 apps).
So, it is in the "nature" of MSYS2 that it puts things in non-standard
directory for MinGW32/64 apps. Probably one can change Emacs configure
to avoid these issue but I wonder, given the simple workaround shown
above, if this is worth the effort.
Instead, it would interesting, to understand why removing the configure
option, "--without-imagemagick", with the MinGW64 ImageMagick package
installed, configure enables imagemagick support but the build fails
with a linker error.. but this is matter for another thread.. I think.

I concord. Emacs has other kind of problems on Cygwin [*] (see recent
threads on the Cygwin list). Breaking what is working would compromise
an already fragile situation.
Ciao,
Angelo.

[*] On Cygwin, usually I use as configure:
./configure --prefix=/usr/local/Emacs.app --with-w32
--build=x86_64-pc-cygwin --with-wide-int 'CFLAGS=-Ofast -g0 -pipe'
LDFLAGS=-pipe CC=clang
which is very similar to that I use on MSYS2..
