------------------------+---------------------------------------------------
This is a problem I discovered when upgrading from sage-4.5.3 to a
candidate 4.6.2.alpha4. Probably, the problem has existed for a while, it
just "surfaced" or got noticed now.
The problem is that the file
`sage/algebras/quatalg/quaternion_algebra_element.cpp`
is '''not''' recreated from the corresponding .pyx file when upgrading.
This then causes a compile error.
The file `sage/algebras/quatalg/quaternion_algebra_element.pyx`
includes (using Cython's `include` statement) `sage/ext/gmp.pxi` and the
latter file was changed some Sage versions ago.
The following happens:
