More minor MSVC code fixes.

However, this code doesn't compile with MSVC9.0 for a few reasons:

1. libguile.h comes with its own scmconfig.h which contains HAVE_STDINT_H
whereas MSVC doesn't have that. This is stupid guile which doesn't accept
the fact that the user uses a different compiler than how they compiled guile.

2. Some initializations are not supported: Account.c:3312 etc.

3. The C99 "designated initializers" of e.g. Account.c:4661 ff. (r17724,
bug#539957) are not supported by MSVC9.0 - this is the hardest problem
of these all.
