One possibility would be to steal the code from cmucl or clisp.  Cmucl
uses stat functions, I think, to walk the directory.

While I'm asking, can we also get a ensure-directories-exist?  This is
useful with mk defsystem.  For now, I just hacked a version that
basically calls mkdir -p. :-)

Also, gcl seems to have define-compiler-macro, but it's in the SYSTEM
package, not COMMON-LISP.  I tried (with maxima) to import the symbol
into COMMON-LISP, but got symbol conflicts.  I couldn't figure out how
to get rid of the offending symbol.

It's very nice to see some development on gcl once again!
