Due to vacation I only just checked now. The patch breaks the Cygwin
build. Especially __tzinfo_type has to be exposed from a public header
in newlib.
So what about the attached patch instead?

Subject: [PATCH] libc/time: Move internal newlib tz-structs into own header
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
As discussed in GCC bug 97088
(https://gcc.gnu.org/bugzilla/show_bug.cgi?id=97088), parameters in
prototypes of library functions should use reserved names, or no name
at all.
This patch moves the internal struct __tzrule_struct to its own
internal header sys/_tz_structs.h. This is included from newlib's
time code as well as from Cygwin's localtime wrapper.
