#'si::stat returns a list with car in '(:link :file :directory) or nil,
never resolving links
#'truename will resolve symlinks
Will this work?

OK, I fixed some in truename, but if you find others, it would be
helpful if you could supply the input triggering the wrong type of
error. I fixed delete-file for you a few cycles ago.

OK, fixed now. Thanks!
Please don't clutter your source with #+-gcl -- it is better if you
write to, and gcl supplies, the common lisp standard, at least by the
time we're done.
You should even be able to use safety settings if you want, but I don't
think you should in your final version. safety puts in type checks
everywhere, and these are almost always redundant, and effectively foil
the most important compiler optimizations, depending on how 'safe' is
defined. Typically you develop using safe code, and then put your own
checks where you want them at the top, or rely on some standard
non-inlined function call to do the checking for you.
gcl defines 'safe' thusly:
0 - no type checking, supplied check-type treated as a type assertion
1 - keep supplied visible check-type calls, but omit those in inlined
children
2 - keep explicit check-types in all children
3 - no inlining, all variables of type t, no type inference, all checks
in place.
One of the reasons the gcl build is so slow is we bootstrap first in
safe mode, and then use that to compile according to the safety
specified in each function.
So your original reported problem with safety 3 is a bug we should fix
before we're through.

Common lisp specifies an implementation should define a constant
call-arguments-limit which is at least 50. In GCL, it is 63. So if you
want to write common lisp code, you should not pass more than 49
arguments or conditionalize on the 'call-arguments-limit constant. The
former is the recommended route, as its exceedling easy just to arrange
your calls to pass a list, which is most often what the implementation
will do for you anyway with so many arguments.

Thanks! This is fixed now.

My results now are:
42 passing and 6 failing
failing test(s): asdf-pathname-test.script test-compile-file-failure.script
test-logical-pathname.script test-run-program.script
test-system-pathnames.script test-utilities.script
If you could summarize the issues here, that would be helpful. I know
there is a logical pathname issue. I'll work on that now.
Take care,
