--- Comment #2 from Daniel Starke <daniel.f.starke at freenet dot de> ---
Minimal test case on MSys/MinGW:
echo '#include <stddef.h>' | gcc -MD -MF - -fsyntax-only -x c -
Result with gcc 9.3.0:
-: \
e:\msys\mingw64_9.3.0\lib\gcc\x86_64-w64-mingw32\9.3.0\include\stddef.h \
[...]
Result with gcc 10.1.0 (':' in path was quoted):
-: E\:/msys/mingw64/mingw/include/stddef.h \
[...]
