Subject: compiling mmap?

Hi,
I'm having some trouble getting Guy's mmap to compile on my box. I was 
certain that I had compiled it once before; but now I can't get it to 
work. This is on MacOSX 10.3.3 (powerpc-darwin7.0). The initial failure 
was that MCL_CURRENT and MLC_FUTURE are not defined:

mark@imac% make
gcc -fno-common -g -O2  -fno-common -pipe -fno-common 
-DHAVE_RB_STR_LSTRIP -DHAVE_RB_STR_MATCH -DHAVE_RB_STR_INSERT 
-DHAVE_RB_STR_CASECMP  -I. -I/usr/local/lib/ruby/1.9/powerpc-darwin 
-I/usr/local/lib/ruby/1.9/powerpc-darwin -I.   -c mmap.c
mmap.c:1:2: invalid preprocessing directive #def
mmap.c: In function `Init_mmap':
mmap.c:1726: error: `MCL_CURRENT' undeclared (first use in this 
function)
mmap.c:1726: error: (Each undeclared identifier is reported only once
mmap.c:1726: error: for each function it appears in.)
mmap.c:1727: error: `MCL_FUTURE' undeclared (first use in this function)
make: *** [mmap.o] Error 1

It appeared that they were supposed to be defined in 'mman.h', so I 
looked in there:
---

#ifdef _P1003_1B_VISIBLE
/*
  * Process memory locking
  */
#define MCL_CURRENT	0x0001	/* Lock only current memory */
#define MCL_FUTURE	0x0002	/* Lock all future memory as well */

#endif /* _P1003_1B_VISIBLE */

---
...and a quick search suggests that _P1003_1B_VISIBLE is undefined.

#defining _P1003_1B_VISIBLE at the top of mmap.c allows it to compile, 
but running 'make test' generates a bus error on the 13th test.

Any help would be greatly appreciated.

thanks,
