Hello,

I am trying to grovel some constants from libraw1394 and came across this problem:

libraw1394/csr.h contains: #define CSR_REGISTER_BASE 0xfffff0000000ULL

Grovelling this using (include "libraw1394/csr.h") (constant (+csr-register-base+ "CSR_REGISTER_BASE")) sets +csr-register-base+ to -268435456.

This is with the current version of cffi from darcs on SBCL 1.0.25 (Linux x86).

I too use this configuration and I get (cl:defconstant +csr-register-base+ 281474708275200)

What gcc version are you using ? Could you compile and run the attached C file and tell me what it reports ?
