Sorry I did not answer this question before. I inspected your configuration logs and ecl_long_long_t is defined. Thus :LONG-LONG should be in *features*. If :LONG-LONG is in *features* then the compiler must support this type and ECL indeed does. However, CFFI might not. Indeed if you look at CFFI's sources you will find this:

    #+x86-64 (:long-long :long "long long")
    #+x86-64 (:unsigned-long-long :unsigned-long "unsigned long long")

which should actually read

    #+:long-long (:long-long :long-long "long long")
    #+:long-long (:unsigned-long-long :unsigned-long-long "unsigned long long")

I am attempting to use long-long (in iolib, it uses it).

heres the code that produces the error:
(macroexpand-1 '(CFFI-SYS:%FOREIGN-FUNCALL "lseek64"
                                            (:INT 1 :long-long 2
                                             :INT 1 :long-long)
                                            :CONVENTION
                                            :CDECL
                                            :LIBRARY
                                            :DEFAULT))

and the expanded form:

(FFI:C-INLINE ((CFFI-SYS:%FOREIGN-SYMBOL-POINTER "lseek64" NIL) 1 2 1)
             (:POINTER-VOID :INT :LONG-LONG :INT)
             :LONG-LONG
             "((long long (*)(int,long long,int,...))(#0))(#1,#2,#3)"
             :ONE-LINER
             T
             :SIDE-EFFECTS
             T)


I dont know how ecl determines if long-long is supported, but gcc
definitely supports long-long and im just getting the error

;;; OPTIMIZE levels: Safety=2, Space=0, Speed=3, Debug=3
;;;
;;; Error:
;;;   * Unknown representation type :LONG-LONG


Ive looked in the configure script and have found flags to turn on
long-float, uint64_t, but no long-long.
