>    Building png with clang 15 results in an error:
>    
>        contrib/libtests/pngvalid.c:11662:4: error: call to undeclared function 'feenableexcept'; ISO C99 and later do not support implicit function declarations [-Wimplicit-function-declaration]
>           feenableexcept(FE_DIVBYZERO | FE_INVALID | FE_OVERFLOW);
>           ^
>    
>    This is because clang 15 introduced this new warning, and fenv.h only
>    declares feenableexcept() when compiling for C standards before C11.
>    
>    The least disruptive way to solve this is to make the port build with
>    USE_CSTD=gnu89.
