redefinition of 'struct timespec'

[inunix3]

When trying to compile SDL_mixer from sources along with my project, I get this error (output from ninja generated by cmake):

It seems that the commit which introduced this bug is afdec3e. Checking out some older commit before the native linux MIDI was added helps to compile SDL_mixer.

This error appears on both clang and gcc.

My system is Arch Linux x86_64, kernel version is 6.13.2-arch1-1. Version of alsa-lib, which owns /usr/include/alsa, is 1.2.13-1.
