FWIW, the getopt version from 1998 needed the following patches to make
in work in C++. Taken from GNU gperf. Maybe that might help you.

getopt.c is a modified version of the getopt.c found in the glibc snapshot
on 1998-04-14. Below the patch that has been applied to this file. The glibc
maintainer has been informed of these patches.
