Hah, you're right: with that,

In file included from /usr/include/selinux/label.h:9:0,                from label.c:40:
/usr/lib/gcc/x86_64-redhat-linux/6.3.1/include/stdbool.h:34:0: warning: "true" redefined#define true 1
In file included from ../../src/include/postgres.h:47:0,                from label.c:11:
../../src/include/c.h:206:0: note: this is the location of the previous definition#define true ((bool) 1)

and likewise for "false".  So that mystery is explained.

I stand by my previous patch suggestion, except that we can replace
the parenthetical comment with something like "(We don't care if
<stdbool.h> redefines "true"/"false"; those are close enough.)".
