Which you already fixed:
commit 4c49accf8997da21be19be0396b2a88f33b9f949

libc/include/math.h: Remove parameter name
As discussed in GCC bug 97088
(https://gcc.gnu.org/bugzilla/show_bug.cgi?id=97088), parameters in
prototypes of library functions should use reserved names, or no name
at all.

That was fixed in newlib a few months ago as well:
