Problem with getopt on CentOS 5.8

[Christian Egli]

Hi all

The liblouis[1] project uses the getopt-gnu, progname and version-etc
modules from gnulib.

We have a developer on CentOS 5.8 who can no longer compile. Make fails
in getopt.h with the following error message:

> In file included from /usr/include/unistd.h:837,
>                  from ./unistd.h:43,
>                  from ../../gnulib/unistd.c:3:
> ./getopt.h:232: error: expected ',' or ';' before '_GL_ARG_NONNULL'
> ./getopt.h:238: error: expected ',' or ';' before '_GL_ARG_NONNULL'
> ./getopt.h:242: error: expected ',' or ';' before '_GL_ARG_NONNULL'
> make[3]: *** [unistd.lo] Error 1
> make[2]: *** [all-recursive] Error 1
> make[1]: *** [all] Error 2
> make: *** [all-recursive] Error 1

He uses the following versions of the autotools:

> autoconf (GNU Autoconf) 2.59
> automake (GNU automake) 1.9.6
> gcc (GCC) 4.1.2 20080704 (Red Hat 4.1.2-52)

Unfortunately I cannot reproduce the problem on my CentOS 5.8 virtual
box image. Is there anything the developer can do locally on his machine
to narrow the problem down?

Thanks
Christian
