I confirm it works with CBIPs in Guile-R6RS-Libs, but I had to make this small change: http://repo.or.cz/w/guile-r6rs-libs.git?a=commitdiff;h=dfab2fe21f82bc40cfdf9a3a3eeb6936d5935c8c IOW, with Guile up to 1.8.5, it was harmless to leave `read_buf_size' uninitialized (actually, zeroed), which was OK since CBIPs don't use it, but the change in `scm_c_read ()' makes it necessary to initialize it. It's probably a reasonable expectation, though. Please commit! Thanks, Ludo'.
