[Debian-med-packaging] Bug#922776: libhmsbeagle : FTBFS on ppc64el - cannot convert ‘bool’ to ‘__vector?=?=(4) bool =?UTF-8?Q?=?UTF-8?Q?int’ in assignment

[Thierry Fauck@linux.ibm.com]

Hi Andreas,

Sounds like my report was missing some info - sorry about that.
When we compile it stops with message
              cannot convert ‘bool’ to ‘__vector?=(4) bool
=?UTF-8?Q?int’ in assignment

Searching for that I found a couple of occurences  and mainly bug
gcc.gnu.org/bugzilla/show_bug.cgi?id=58241 
which is named *Bug 58241*
<https://gcc.gnu.org/bugzilla/show_bug.cgi?id=58241> - [PPC/Altivec]
altivec.h inclusion in -std=c++98..11 causes bool to be redefined

This bug reports that building with -std=gnu++11 does not fail. So I
checked that this is also true with our package.

Trying other workaround like #undef bool around #include <altivec.h>
doesn't work because it is not implicitely specified
in the code, so I haven't find how to do it right.now.

However I don't know what changing -std= value implies.

Is that better ?
Thanks
