[PHP-DEV] Re: Bug #2071 Updated: Compilation error in "functions/sysvshm.c" From: Mats Bredell (Mats.Bredell <email protected>)

Yes, that fixes it.

The conflict is in <sys/seg.h> which gets included through other include files:

-----8<-----
struct segstate {
        ushort segflag; /* type of segment */
        ushort num_segs; /* number of segments */
        union {
                uint mfileno; /* file discreptor */
                struct shmid_ds *shmptr; /* shared memory descriptor */
                ulong srval;
        } u_ptrs;
};
#define shm_ptr u_ptrs.shmptr
#define segfileno u_ptrs.mfileno
#define ss_srval u_ptrs.srval
-----8<-----

The name shm_ptr doesn't seem to appear in any other include files, so #undef'ing
it should work without causing any bad side effects.
