Hello, Chris,
thanks for testing it right away. It was a stupid mistake on my part, of course.
To get around the build error I had to define macros in the build-script.
“-DHAVE_MKTIME -DHAVE_TIMEGM”
Unfortunately, configure --extra-cflags does not work as expected
So I set CFLAGS before the call to configure and forgot to append the existing
flags ${CFLAGS} :-(
