Hmm... This was what I thought. I build the W64 binaries of Emacs, and I 
DO use mingw64_shell.bat, where:

$ echo $PATH
/mingw64/bin:/usr/local/bin:/usr/bin:/bin:/c/Windows/system32:/c/Windows:/c/Windows/System32/Wbem:/c/Windows/System32/WindowsPowerShell/v1.0:/usr/bin/vendor_perl:/usr/bin/core_perl

$ gcc -v
Using built-in specs.

and I build with

$ ./autogen.sh
$ ./configure --prefix=/Emacs --with-wide-int --build=x86_64-w64-mingw32 
--without-imagemagick 'CFLAGS=-I/mingw64/include/noX -Ofast -g0 -pipe' 
LDFLAGS=-pipe

$ make -j3


If I remove the "--build=x86_64-w64-mingw32" option to configure, the 
build is configure for x86_64-pc-mingw64,

[...]

and 'make -j3' fails at some point.. Instead, with that configure 
option, the build is configure for 'x86_64-w64-mingw32' and it is 
completed successfully...

So, may you explain how you build Emacs on MSYS2?

TIA,
 Angelo.
