[PATCH 0/7] prefix discovery at runtime (on Windows)

[Steffen Prohaska <prohaska@zib.de>]

Hi,
This patch series fixes discovery of the installation prefix at runtime on
Windows.  It introduces a compile flag RUNTIME_PREFIX, which can be set to
explicitly request prefix computation at runtime.

Apologies for proposing such large changes that late in the release cycle.
Maybe we want to postpone the series until 1.6.0.1 or even 1.6.1.  Note however
that in this case we should consider not releasing 1.6.0 on Windows because the
current solution in master does not reliably read the system wide configuration
on Windows.

We probably won't see a Windows installer before mid of September anyway,
unless someone temporarily takes over the position of the msysgit maintainer
until I return from holidays.  I'll be completely offline from August 25
until September 13.

        Steffen
