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.

So on Windos, where unsigned int is the same as unsigned long, the two existing overloads of numeric ctor are ambiguous. Bummer. It's better to convert these prototypes to uint32_t, uint64_t from than add more overloads for size_t. This way, we need to maintain two overloads, rather than three. -richy.
