genreflex on Mac Snow Leopard

Hi,

I'm trying to get Reflex dictionaries working on Mac Snow Leopard using ROOT 5.26.00b and find that genreflex chokes on the system stdlib.h. Has anyone experience this problem and found a solution?

Read on for some details.

The system is:

---

I see the problem when building the Relax set of dictionaries. The build is failing in the HepMC dictionaries, which happen to be the first ones CMT decides to build:

The area of stdlib.h where the initial two failures are is this:

---

    271 #ifdef __BLOCKS__
    272 int atexit_b(void (^)(void));     273 void *bsearch_b(const void *, const void *, size_t,     274 size_t, int (^)(const void *, const void *));     275 #endif /* __BLOCKS__ */

---

I have never seen this use of "^" in C/C++. Does anyone know what it means?

And, to the bigger question, any suggestions about how to proceed?

Thanks,
-Brett.
