[Larceny-users] ctools flag for 64 bit systems.

[Ray Racine]

FYI, 

Nice to see the FFI using cc to determine offsets in cstructs.  
I was segfaulting on my AMD64, Linux system however as gcc defaults to
64-bit compilation.  

After adding the -m32 flag to the cc options its working fine.

I have a bit of code from awhile back where I did a hand layout for
using Larceny with libusb.  I'll try and redo it this weekend to use the
ctools approach.
