Re: new snapshot, and a huge set of coreutils test results

[Bruno Haible]

Here's a closer look to the tests from gnulib:

> go.2008.04.14.07.01.55.log:FAIL: test-frexpl      IRIX 6.5, gcc 3.4.3, NaN 
> argument
> go.2008.04.14.07.01.55.log:FAIL: test-isnanl-nolibm    same
> go.2008.04.14.07.01.55.log:FAIL: test-vasprintf-posix  same

Apparently isnanl (0.0L / 0.0L) yields false instead of true. It does not
use the gnulib replacement. With gcc 2.95.2 on IRIX 6.5, I get the same
configuration results, i.e. it uses the gcc builtins, but no test failure.
Maybe the attached fix will do it.

These look like glibc bugs, possibly introduced by Gentoo.

The used compiler (c89) apparently does not support 64-bit integers. A better
compiler (cc) is available in the same directory. It does not make sense to
use c89 under these conditions.

Maybe already fixed by Eric's recent changes,

These were reported and fixed in gettext on 2007-11-28. (libintl.h had a
#define fprintf that undid the one from gnulib.)
