Before commit 02d5467e9f43dac05f04999e387108ca4c8ba140 "-MT" was followed by "-U_FORTIFY_SOURCE", but now it's "-I/mingw/include/SDL" which gets swallowed.Neither is/was correct, does escaping $@ in rules make (i.e. \$@) have any effect?
Changing it to \$@ makes it compile again:$ grep MMD rules.mak QEMU_CFLAGS += -MMD -MP -MT \$@
