* guix/build/syscalls.scm (define-bits): Do not define NAMES... as
top-level variables since that prevents literal matches in 2.2.
Instead, determine constant values at expansion time.
Fixes a regression introduced in 7447aa36e1.
Reported by Ricardo Wurmus.
* guix/utils.scm: Revert 7447aa36e1. Use
#:prefix for (ice-9 iconv) to support both 2.0 and 2.2.
In Guile 2.2, (rnrs io ports) exports 'bytevector->string', which
conflicts with that of (ice-9 iconv).
* guix/utils.scm: Hide 'bytevector->string' from (rnrs io ports).
* guix/ui.scm (right-arrow): Call 'set-port-encoding!' to set PORT's
encoding; remove use of 'with-fluids'. This is for compatibility with
Guile 2.2 where the encoding of string ports is not influenced by
%DEFAULT-PORT-ENCODING.
* tests/ui.scm ("show-manifest-transaction"): Likewise.
* guix/ui.scm (fill-paragraph): Don't use '_' as a pattern variable

In glibc-2.25 a dependency on "linux/falloc.h" was added.

It doesn't make sense to run non-test executables (which is what "dub run"

This avoids a situation where the "debug" output would contain separate
(and different) .debug files for "libfoo.so" and "libfoo.so.0.0", even
though "libfoo.so" is actually a symlink to "libfoo.so.0.0".
* guix/build/gnu-build-system.scm (strip): Remove 'file-exists?' call in
'for-each' lambda. Pass a predicate to 'find-files' to restrict the
result to regular files.
* guix/scripts/copy.scm (open-ssh-session): Replace userauth-agent! by
userauth-public-key/auto!. This way, if ssh-agent is not run,
default ssh key (~/.ssh/id_rsa) will be used as a fallback.

* guix/scripts/container/exec.scm (guix-container-exec): Capture the value of

others have more functionality, providing that the terminal was capable of
enabling that functionality in the first place.
