You don't even need to play with autoconf, just do

#define FUSE_USE_VERSION 26
#include <fuse.h>

...

#if FUSE_VERSION >= 26
	fuse_main(argc, argv, &my_op, NULL);
#else
	fuse_main(argc, argv, &my_op);
#endif

But all this is only important if you need some API features from
2.6.x/2.7.x.  Otherwise you can just use the old API unconditionally:

#define FUSE_USE_VERSION 25
#include <fuse.h>
