Minor note:

The file srfi/113/test.sld has two cases of duplicate definitions (which
I believe are not legal): Both cases redefine whole4 and they are on
lines 265 & 272 and 539 & 546.

At first I thought this problem may be one inherited from the SRFI 113
code but, based on a quick look at it, I think it doesn't affect SRFI
113's version.
