Here's the promised patch. Note that it is not intended to be applied
as-is to ginac source tree. But it's to show what are the required changes
to make ginac compilable under VC++ and to be able to run the test
suite.

Some comments about the patch:
- the __alignof__ vs. __alignof could be turned into a configure test
- VC++ does not support __func__ macro, so I changed it into __FILE__
- in exprseq.cpp, I had to add a dummy function to make VC++ instantiate
expreseq::info(); don't know why...
- when trying to fix issues with iterators, I might have broken the
normal flow of ginac (although the test suite seems to run fine), so these
changes have to be reviewed
- I'm pretty sure there are other locations with iterator issues, but they
didn't produce any problem in the test suite, so I didn't notice them

Bye,
Michael.
