Subject: bug#43232: [PATCH] gnu: jack-2: Update to 1.9.14.
Date: Mon, 14 Sep 2020 21:25:25 -0700

* gnu/packages/audio.scm (jack-2): Update to 1.9.14.
[arguments]: new 'declare-for-int phase after unpack that declares 'i in the
for initialize statement.  Add -lstdc++ to LDFLAGS 'set-linkflags phase
ensures -lstdc++ is at the tail.

This fixes issues that cause jack-2 to not build on system aarh64-linux.
