Current snapshot e4982b2 fails to build:

[   14s] In file included from libavutil/fixed_dsp.c:49:
[   14s] libavutil/fixed_dsp.h:53:10: fatal error: mathops.h: No such file or directory
[   14s]    53 | #include "mathops.h"
[   14s]       |          ^~~~~~~~~~~
[   14s] compilation terminated.
[   14s] make: *** [ffbuild/common.mak:81: libavutil/fixed_dsp.o] Error 1

[jengelh]

Possible workaround: copying all the mathops.h from ffmpeg-8, or using ./configure --disable-avutil.
