Thanks for reporting the problem.

What compiler and compiler version are you using? For example, if you're 
using GCC, what is the output of the 'gcc --version' command?

What options are you giving the compiler?

Is the problem new to tzdb-2023c, or do you see it with earlier versions 
of tzdb?

Does the problem go away if you compile with the -DPORT_TO_C89 compiler 
option? E.g.,

make CFLAGS='-DPORT_TO_C89'

The PORT_TO_C89 flag is documented in the Makefile.
