Hi, Steve,

I wonder if we can simply determine whether the OS supports AIO by sysconf(_SC_ASYNCHRONOUS_IO). The following is run on Solaris 2.6 for SPARC:

$ cat q.c
#include <unistd.h>
#include <stdio.h>

main()
{ printf("%ld\n", sysconf(_SC_ASYNCHRONOUS_IO)); }
$ gcc q.c
$ ./a.out
1

I assume if it returns 1, it supports it.
