Helooooooooooo

When compiling on IRIX 6.5.8 with gcc 2.95.2 debug builds are using
'-pedantic' which triggers the following warning 'ANSI C forbids long
long integer constants'.

It could be considered nice to give us that information but the plain
truth is that in that configuration long long constants work
flawlessly as 'configure' shows us defining HAVE_LONGLONG and HAVE_LL.

The only way of getting rid of this warning on the autobuild table for
that platform and configuration in files lib518.c and lib537.c is just
to not count them as warnings, just as it has been done for ages for
file src/main.c filtering it.
