The __INSIDE_CYGWIN_foo__ naming scheme seems to be what is used
elsewhere for similar purposes, hence my choice here.

I just followed what I observed with glibc:
$ cat test.c
#include <sys/types.h>
#include <stdio.h>
int
main(void)
{
int maj = 4, min = 64; /* /dev/ttyS0 */
printf("%d, %d = %d\n", maj, min, makedev(maj, min));
return 0;
}
$ gcc -O0 test.c
$ nm a.out | grep " U "
U __libc_start_main@@GLIBC_2.0
U gnu_dev_makedev@@GLIBC_2.3.3
U printf@@GLIBC_2.0
$ gcc -O1 test.c
$ nm a.out | grep " U "
U __libc_start_main@@GLIBC_2.0
U printf@@GLIBC_2.0
