You are right, command.com is the reason.

So I have not checked for a shell that comes with mingw.
For cygwin-bash the problem was, the avr-gcc is build
under mingw and expects DOS filenames, like c:/src/main.c
but the bash hands over /cygdrive/c/src/main.c, so that
avr-gcc could not open the file. (you can not mixup
mingw and cygwin based programs, another issue is, that
the PATH variable is of importance, because there are some
tools with equal names in DOS and MinGW but different
command line options.)
As soon as I'm back at my Windows Desktop (Tuesday),
I will try a shell coming with mingw.

Yes, this would cleanly encapsulate the "-C GNUism"
so that it don't break the make on other Unixes.

Thanks and Best Regards
