cyrus-sasl 2.1.28 triggers compilation errors with gcc 14.1.0

[dschepler]

Trying to build the latest release https://github.com/cyrusimap/cyrus-sasl/releases/download/cyrus-sasl-2.1.28/cyrus-sasl-2.1.28.tar.gz on my system with gcc 14.1.0, I get a couple compilation errors:

(In response to an earlier comment on a different issue: I do see lines #ifdef HAVE_TIME_H // #include <time.h> // #endif in lib/saslutil.c. However, in a search through the source code and build directory, the only files that contain HAVE_TIME_H are lib/saslutil.c and mac/libdes/src/speed.c. I don't see anything in the configure script that would actually test for time.h and set HAVE_TIME_H. I also don't see any such include in plugins/cram.c.)

duplicate #838

[flowerysong]

cram.c and the general check for time.h were fixed in 266f0ac; cram.c was then removed in 5436909.

[quanah]

Thanks. Generally the 2.1 tree is dead, reporting errors should be done against current master.

[dschepler]

OK, so you're saying this comes under the heading of #835 then?

[quanah]

If you find problems with the master branch that don't already have issues, feel free to file them. there are no new planned releases for the 2.1 series.
