On a Solaris 5.10 system I have access to, /opt/csw/include/getopt.h is a GNU libc include file from 1997. It is probably the same file that you are using, as the declaration is on the same line (118). I know it is possible to compile on this system with the right environment because it's done successfully on the OpenCSW buildfarm. (See https://buildfarm.opencsw.org/buildbot/waterfall?category=texinfo for logs). I tried compiling Texinfo 6.3 the same way and didn't get the same error, so it is probably due to a change in Gnulib. I found in the older gnulib, the _getopt_internal had been redefined as rpl_getopt_internal after the system header had been read, so the definition clash did not occur. I'm copying bug-gnulib into this email to see if the Gnulib developers can take this any further. I believe the section that #define's the function names is now in getopt-pfx-ext.h. _getopt_internal is not redefined there. Formerly, I believe it was in getopt.h that _getopt_internal was redefined, like this: # define _getopt_internal __GETOPT_ID (getopt_internal)
