[GSLL-devel] grid (un)signed-byte 64 error

[Liam Healy]

If you are on 32-bit hardware, you do not have 64 bit types.  Try
this: (cffi:foreign-type-size :long)
if it says 4, you're out of luck.  If it says 8, you should be all
set.  That result is determined by the hardware, the OS, and the Lisp
implementation, not by GSLL/grid.
