* [Bug libgcj/44216] New: [4.6 regression] All libjava tests fail on IRIX 6.5: ld warns about -no-merge-exidx-entries

Since the introduction of the configure check for the --no-merge-exidx-entries
linker option, all libjava tests fail on IRIX 6.5:
output is:
(null): WARNING 1 : Unknown option: -no-merge-exidx-entries (ignored).
FAIL: linking PR9577
The problem is that the SGI ld warns about unknown options as above, but still
exists with status 0. None of the options to suppress errors/warnings has an
effect on this, neither -LD_MSG:error=1 nor -LD_MSG:off=1 nor -woff 1.
I've found no good way to handle this generically, since the AC_LINK_IFELSE
macro only logs stderr of the link command to conftest,err and the warning
goes to stdout. I could of course simply set libgcj_cv_exidx=no for
mips-sgi-irix6.5, but perhaps there's a cleaner solution I'm just not seeing?

Paolo, do you happen to have an idea how to handle this cleanly?

What if you call AC_LANG_WERROR just before the test? This wouldn't be a final
patch because then you need to restore the previous value, but it's a start.
Ralf, maybe we want in Autoconf (and hence in override.m4) a mechanism to
push/pop the AC_LANG_WERROR state?

Isn't there such a mechanism already? If not, then there was at least a
proposed patch (series) to add such a while ago, I don't recall whether/why
that wasn't merged.

At least not in Autoconf 2.64. I've found a single instance in the
implementation of AC_PATH_XTRA.
I'll give it a try.

proposed patch
This patch worked for me. It's a hack in that it does the save and restore
using lowlevel autoconf implementation details, but it gets the job done.

The patch needs a fat comment saying what's going on, then it should be okay.
