Projects fail to build with C23

[PatchMixolydic]

Trying to build a simple project with EXTRA_FLAGS=-std=c2x make -f $GDK/makefile.gen yields the following:

In file included from /home/patchmixolydic/mars/m68k-elf/inc/genesis.h:6,
                 from src/main.c:1:
/home/patchmixolydic/mars/m68k-elf/inc/types.h:113:12: error: two or more data types in declaration specifiers
  113 | typedef u8 bool;
      |            ^~~~
/home/patchmixolydic/mars/m68k-elf/inc/types.h:113:1: warning: useless type name in empty declaration
  113 | typedef u8 bool;
      | ^~~~~~~
make: *** [/home/patchmixolydic/mars/m68k-elf/makefile.gen:171: out/src/main.o] Error 1

This may be related to N2934, which introduced a bool keyword/predefined macro.
