It has changed, allright, but the change wasn't supposed to break
anything.

I cannot reproduce this on my system. I used a simple program that
simply echoes its argv[] array, and invoked that program with a
command such as the one you show above. The command-line arguments
displayed by the program were devoid of any quotes, as expected.
So I think there's some factor involved here that you didn't
describe. Some relevant factors might be:
. what shell is being used by Make?
. is c:/Rtools/mingw_64/bin/gcc.exe a native Windows program, or is
it a Cygwin or MSYS program? or maybe it is some wrapper script?

I'm not sure I understand what that means. Could you try the binaries
from here:
https://sourceforge.net/projects/ezwinports/files/make-4.2-without-guile-w32-bin.zip/download
and see if the problem persists? (If you need Make with Guile
support, you will find one right near the above one.)

The official MinGW Make build does not use the Posix configury stuff,
it uses a dedicated batch file, build_w32.bat, so there's no simple
answer to your question. I myself never used the configure script and
the Posix Makefiles it creates to build the native Windows port of GNU
Make, I always use that batch file.
