[systemd-devel] Old definitions

[Dennis Semakin]

Hi,

I'm currently compiling systemd-194.
Very often I get the error about undeclarated definitions MS_REC, MS_PRIVATE, MS_MOVE... in mount func.
I know that's because of old glibc headers...
But. may be it would be useful to write something like that:

#ifndef MS_REC          /* May not be defined in older glibc headers */
#define MS_REC 16384
#endif

#ifndef MS_PRIVATE      /* May not be defined in older glibc headers */
#define MS_PRIVATE (1<<18) /* change to private */
#endif

#ifndef MS_SLAVE        /* May not be defined in older glibc headers */
#define MS_SLAVE (1<<19) /* change to slave */
#endif

#ifndef MS_SHARED       /* May not be defined in older glibc headers */
#define MS_SHARED (1<<20) /* change to shared */
#endif

For those who didn't want or can update glibc.

Best regards,
Den
