Hello
Pipes are not working in Windows (MSYS2)
here is an example program
(use-modules (ice-9 popen)
(ice-9 rdelim))
(let ((pipe (open-pipe* OPEN_READ "uname")))
(display (read-line pipe))
(close-pipe pipe))
and its output
λ guile -s main.scm
#<eof>
of course `uname` works in the shell (bash
λ uname
MSYS_NT-10.0-19045
the *features* variable signals that pipes are in theory available
scheme@(guile-user)> *features*
$1 = (readline record defmacro debug-extensions values array-for-each
array sort socket net-db regex popen fork EIDs posix readlink-port
chdir-port inexact complex random i/o-extensions i18n current-time delay
threads char-ready? system)
here is the version of guile I'm using
λ guile --version
guile (GNU Guile) 3.0.9

I tried the other `open-pipe` function, to the same result.
Interestingly, `(system "uname")` works as expected.
both `popen` and `pclose` are available as stdio.h functions, I made
sure by writing essentially the same program as above in C.
Thanks!
