Hi, ECL community
I met some problems when compiling usocket on ECL 9.4.0, below is the
error outputs:
=============

=============
I think following code in usocket break above build:
(defun fdset-alloc ()
(ffi:c-inline () () :pointer-void
"cl_alloc_atomic(sizeof(fd_set))" :one-liner t))
It seems that the function "cl_alloc_atomic" doesn't exist anymore.
1. What should we (usocket) do instead in ECL 9.4.0?
2. Is there anyway to detect the exist of "cl_alloc_atomic" in any ECL
versions? (ECL doesn't put any version information in CL *features*,
and we (usocket) want to support more ECL versions as many as possible)
