Probably, I should update gcc also, perhaps you can advise on any
specific configuration to enable / disable etc.
It seems your system doesn't have a working va_arg macro. What
version of irix are you using? What version of gcc are you using?
m4-1.4.11 builds and passes all tests for me with both sgi's compiler
and my gcc-4.2.3 installation:
] ./config.guess
mips-sgi-irix6.5
] /bin/cc -v

] ./configure CC='/bin/cc'

Maybe your gcc is not installed correctly?
However, since m4-1.4.11 has 3 authors, you could work around it
by rewriting the version_etc function to accept author names explicitly:
void
version_etc (FILE *stream,
const char *command_name, const char *package,
const char *version, const char *author1, const
char *author2,
const char *author3, const char *ignored)
{
if (command_name)
fprintf (stream, "%s (%s) %s\n", command_name, package,
version);
else
fprintf (stream, "%s %s\n", package, version);
/* TRANSLATORS: Translate "(C)" to the copyright symbol
(C-in-a-circle), if this symbol is available in the user's
locale. Otherwise, do not translate "(C)"; leave it as-is.
*/
fprintf (stream, version_etc_copyright, _("(C)"),
COPYRIGHT_YEAR);
fputs (_("\
\n\
This is free software: you are free to change and redistribute
it.\n\
There is NO WARRANTY, to the extent permitted by law.\n\
\n\
"),
stream);
/* TRANSLATORS: Each %s denotes an author name. */
fprintf (stream, _("Written by %s, %s, and %s.\n"), author1,
author2, author3);
}
The code in my source is a tad bit different and my C isn't fully up to
snuff. On which line should the explicit authors field be filled
void
version_etc_va (FILE *stream,
const char *command_name, const char *package,
const char *version, va_list authors)
{
size_t n_authors;
/* Count the number of authors. */
{
va_list tmp_authors;
va_copy (tmp_authors, authors);
n_authors = 0;
while (va_arg (tmp_authors, const char *) != NULL)
++n_authors;
}
if (command_name)
fprintf (stream, "%s (%s) %s\n", command_name, package, version);
else
fprintf (stream, "%s %s\n", package, version);
/* TRANSLATORS: Translate "(C)" to the copyright symbol

locale. Otherwise, do not translate "(C)"; leave it as-is. */
fprintf (stream, version_etc_copyright, _("(C)"), COPYRIGHT_YEAR);

stream);
switch (n_authors)

case 0:
/* The caller must provide at least one author name. */
abort ();

vfprintf (stream, _("Written by %s.\n"), authors);

break;
case 4:

You can use line breaks, estimating that each author name
occupies
ca. 16 screen columns and that a screen line has ca. 80
columns. */
vfprintf (stream, _("Written by %s, %s, %s,\nand %s.\n"),
authors);
break;
