Fixing `flush-output-port` for R6RS transcoded ports

Hi! As I reported in #39610 [0], `flush-output-port`, aka `force-output` is no longer working for R6RS transcoded ports. It was still working in Guile 2.0; the regression was introduced in Guile 2.2, via commit "8399e7af5 ("Generic port facility provides buffering uniformly"). I'd be interested

Re: Reading data from a file descriptor

(display "\n"))) (process-fd (acquire-valid-fd)) You could now just implement `acquire-valid-fd' in C and expose it to Scheme, if that is even necessary. If you have the FD available via e.g. an environment variable, `acquire-valid-fd' can be implemented in Scheme as well. Regards, Rotty -- Andreas Rottmann -- <http://rotty.xx.vu/>
