CLN and GiNaC patches for Win64 build

Hi, I reviewed Robert's patches and added some of my own, that were necessary for GiNaC to work with CLN on Win64. They can be viewed on Github: === CLN === https://github.com/jrheinlaender/cln/commits/win64 There are two kinds of patches: - Patches required for Win64 platform (e.g. UL is 32 bit type on that platform). Mostly due to Robert (Number 1-10) - Cosmetic patches to avoid unnecessary compiler warnings (e.g. confusion of class and struct) Most patches I surrounded with #ifdef _M_AMD64 so that other platforms will be unaffected === GiNaC === https://github.com/jrheinlaender/ginac/commits/win64 - Here I removed some old patches that are not required any more because of improvements in MSVC 2015 - And added a few constructors from size_t I hope these patches are OK and can be included in master.

Before, matrix::rank() was hardcoded to use Bareiss elimination, which for some matrices is way too slow (and I had to work around this limitation in my own code). I propose adding an argument that will allow users to select which elimination scheme to use. The argument is the same as matrix::solve() takes (so, solve_algo::*). I've tried to mimic how a similar argument was added to matrix::inverse() by keeping the current set of rank() functions and defining separate ones with the 'algo' argument, with the old ones calling the new ones with solve_algo::automatic. This is instead of using default argument values. I've also put the code that makes the automatic selection of the elimination method into a separate function so that both matrix::solve() and matrix::rank() could share it. There's a bit of similar code in matrix::determinant(), but since the self of determinant algorithms is different from the elimination algorithms, it's not clear if these two could be unified. ----------------------------------------------------------------------- Summary of changes: doc/tutorial/ginac.texi | 14 +++---- ginac/matrix.cpp | 108 ++++++++++++++++++++++++++---------------------- ginac/matrix.h | 4 ++ 3 files changed, 69 insertions(+), 57 deletions(-) hooks/post-receive -- GiNaC -- a C++ library for symbolic computations
