STC showing that sysmacros doesn't work when included indirectly in C99
mode:

$ cat foo.c
#include <sys/types.h>
int main() { return makedev(0,0); }
$ gcc -o foo foo.c
$ gcc -o foo foo.c --std=3Dc99
/tmp/ccT40f0H.o:foo.c:(.text+0x1e): undefined reference to
`_gnu_dev_makedev'
collect2: ld returned 1 exit status

Another STC showing that sysmacros is broken as a standalone header:

$ cat bar.c
#include <sys/sysmacros.h>
int main() { return makedev(0,0); }
$ gcc -o foo foo.c
In file include from foo.c:1:0:
/usr/include/sys/sysmacros.h:14:18: error: expected `=3D', `,', `;',
`asm', or `__attribute__' before `int'
...
