[GiNaC-devel] Patches for compilation with MSVC

[Jan Rheinländer]

Hi,

here are some simple patches to allow the current version (from git) of
GiNaC to be compiled with MS Visual C++:

1. Fix problem with min() and max() macros in MSVC:

2. Fix ambiguous overload of log() (MSVC is more exact here than gcc):
