Did you try building without SIMD support? This is what I see:
list.c: In function ‘list_member_ptr’:
list.c:697:2: warning: ISO C90 forbids mixed declarations and code
[-Wdeclaration-after-statement]
697 | const ListCell *cell;
| ^~~~~
If your build doesn't have USE_NO_SIMD defined, this warning won't appear
because the code in question will be compiled out.
