+Subject: [PATCH] meson: better check for module dlopen dir
+
+The ${LIB} token is a glibc extension, so it is incorrect to
+use it on all Linux. Doing so will break e.g. with musl libc.

+Subject: [PATCH] alsa: get rid of non-portable isinf use
+
+The isinf function returns -1 for negative infinity on glibc, but
+the standard guarantees no such behavior (e.g. in C++ it always
+returns a bool, on musl libc it's a macro that expands to a bool
+expression), saying just that it returns a non-zero value.
+
+This was added in pulseaudio around 15 years ago, and was never
+fixed; pipewire then got the code from it. However, we can portably
+check against -INFINITY instead (from math.h, already included).
