-------------------------+-------------------------------------------------
with gcc 4.9.2, we hit this bug:
[https://gcc.gnu.org/gcc-4.9/porting_to.html Header <cstddef> changes]
The <cstddef> header was updated for C++11 support and this breaks some
libraries which misuse macros meant for internal use by GCC only. For
instance with GMP versions up to 5.1.3, you may see:
{{{
/usr/include/c++/4.9.0/cstddef:51:11: error: â::max_align_tâ has not been
declared
using ::max_align_t;
}}}
This has hit here: #18198, see also
[https://gcc.gnu.org/gcc-4.9/porting_to.html sage-devel thread]
The workaround suggested appears to work. A patch follows shortly.
