I tried to build ffmpeg-3.4.12, which is the last one supporting Windows XP, but it fails to compile the resource file for Windows.
Running verbose build, it prints this output on the console:

$ make V=1
i686-w64-mingw32-windres -I. -Isrc/ --preprocessor "i686-w64-mingw32-gcc -E -xc-header -DRC_INVOKED -MMD -MF libavdevice/avdeviceres.d -MT libavdevice/avdeviceres.o" -o libavdevice/avdeviceres.o /home/carlo/packages/ffmpeg/mingw64-i686-ffmpeg-3.4.12-1.noarch/src/ffmpeg-3.4.12/libavdevice/avdeviceres.rc
/bin/sh: i686-w64-mingw32-gcc -E -xc-header -DRC_INVOKED -MMD -MF libavdevice/avdeviceres.d -MT libavdevice/avdeviceres.o: No such file or directory
make: *** [/home/carlo/packages/ffmpeg/mingw64-i686-ffmpeg-3.4.12-1.noarch/src/ffmpeg-3.4.12/ffbuild/common.mak:86: libavdevice/avdeviceres.o] Error 1

I found a solution by comparing ffbuild/common.mak between this version and the latest 5.1.2, which has already fixed this bug. According to this reply that I received on the mailing list:

a patch already exists in commit f9626d1065c43f1d51afe66bdf988b9f33729440.
Is it possible to apply this patch also to 3.4 branch, to allow building this version on Windows, when an updated release will be made public?

Thank you very much.
