[Bug c/42199] New: A problem with -maltivec

[galtgendo at o2 dot pl]

You'll probably mark this bug as invalid,
as it's not my bug and being on x86, I really can't
provide any info.

http://bugs.freedesktop.org/show_bug.cgi?id=25103

As you may see there, a trivial autoconf test was failing
with -maltivec, but even before upstream made a change
to do that test with g++, instead of gcc, it was working on x86.

That's why I suspect it may be a compiler problem,
that poppler upstream simply masked.

Can you attach the preprocessed source for the configure test that is  
failing? It looks like the context sensitive keywords is causing the  
header to fail to compile.

------- Comment #3 from galtgendo at o2 dot pl  2010-02-21 21:22 -------
There's new input in a different Gentoo bug:
http://bugs.gentoo.org/show_bug.cgi?id=305333

Apparently in certain conditions on ppc, 
bool is both defined and undefined.

Unless you'll see that as bad code on openjpeg side.
