Hello schemers,
the bitwise-bit-count procedure from (rnrs) is wrong for negative
arguments in Guile 2.0.9:
scheme@(guile-user)> (import (rnrs))
scheme@(guile-user)> (bitwise-bit-count #b-101)
$1 = 1
The correct result is -2.
Regards,

Indeed, thanks for the report. Now fixed on the stable-2.0 branch.
