description:
Add my patch for PR 51100 (from 2016) to devel/cdecl.

This fixes a shift-reduce conflict in the parser that causes e.g.
"static const int" to be rejected as a syntax error.

This patch should have been handled by upstream, but there doesn't seem
to be an upstream.

+Fix shift/reduce conflict that makes "explain static volatile int foo"
+not parse. See PR 51100.
+
+Should really be handled by upstream, but there does not seem to be an
+upstream.
