I don't know much about this, so I might not help much. lib-src/
contains some getopt* files that ought to provide a definition of
getopt_long if your system does not have one. Can you figure out why
they are not working for you?

getopt1.c contains a definition of getopt_long, and your command-line
above shows getopt1.o being included in the compile command.

Did the file getopt.h in your lib-src directory get generated? Is
etags.c finding it when it gets compiled?

What are the values of GETOPT_H and GETOPTDEPS in your
