When compiling with mingw on Ubuntu 23.10, I get the following compiler
error:
../../lib/eal/windows/eal_memory.c:77: error: "MEM_REPLACE_PLACEHOLDER" redefined [-Werror]
77 | #define MEM_REPLACE_PLACEHOLDER 0x00004000
|

5710 | #define MEM_REPLACE_PLACEHOLDER 0x4000
and a similar error for MEM_RESERVE_PLACEHOLDER. These errors can be
fixed by wrapping the two defines in #ifndef .. #endif blocks.

Yep, duplicate. I'll reject my patch in patchwork. Hopefully the patch
above will be merged soon to make this issue go away! :-)
