Yes, mtext[] is not a valid ISO C construct.
The structures of the SysV IPC interfaces are generally not
defined by system headers, although some implementations
choose to provide them.
Thus the rule should be: If autoconf finds the definition, we
use it, otherwise we rely on our own, namespace-protected
version. Example:
#ifdef HAVE_STRUCT_SYSMSG
typedef struct sysmsg php_sysmsg;
#else
typedef struct {
long mtype;
char mtext[1];
} php_sysmsg;
#endif

Unless it decreases the quality of the code, it should stay
in (I have not looked at it myself).
