from https://man7.org/linux/man-pages/man3/isnanf.3.html
"Note that these functions are obsolete. C99 defines macros
isfinite(), isinf(), and isnan() (for all types) replacing them."
Building JDK with musl libc gives the error:
-------------------
src/hotspot/share/utilities/globalDefinitions_gcc.hpp:115:39: error: 'isnanf' was not declared in this scope; did you mean 'wscanf'?
115 | inline int g_isnan(float f) { return isnanf(f); }
-------------------
This is because musl libc does not define isnanf. It only declares isnan:
