Now to R6RS. Section 6= .4 says that auxiliary syntax describes a syntax binding. Section 12.4 of t= he R6RS Library Report defines `...' as auxiliary syntax. The example d= efinition of `case' in Section 12.5 ibid. shows explicitely that auxili= ary keywords are matched using `free-identifier=3D?' (in this example, = `else'). Also, in all other regards with respect to auxiliary syntax R6= RS does not differ from R7RS.

P.S.: I just noticed that Guile does not= export `...' from (rnrs base), which is an incompatiblity to the R6RS = that is not mentioned by the following list, I think: https://www.gnu.org/software/guile/manual/html_node/R6RS= -Incompatibilities.html#R6RS-Incompatibilities. Likewise, identifiers l= ike `else' and `=3D>' are not exported by the Guile version of `= (rnrs base)'. Oddly enough, other auxiliary syntax like `unquote' i= s being bound.
