Well yeah, that's the same fix as mine in 0b40da5 . I would be more interested in a way to reproduce this build failure in a CI pipeline, particularly in #1243. But the Alpine build succeeds there: https://dev.azure.com/tommbrt/tommbrt/_build/results?buildId=9127

I don't see how the question of C99 compliance is relevant here, esp. because fluidsynth is a C89 project currently.

You're correct, by bad. Let me correct that.

THe issue was reproduced on Gentoo with musl libc. https://bugs.gentoo.org/906150. I don't know if alpine is doing something special.

Ok, thanks for the pointer. I'll double check any compiler flags with the apline build when I find the time.

According to #1229 this is a problem on Alpine as well, but this issue lacks precise instructions on reproducing it.

This should be strings.h
