[PATCH 1/7] Windows: Add workaround for MSYS' path conversion

[Steffen Prohaska <prohaska@zib.de>]

MSYS' automatic path conversion causes problems when passing paths as '-D'
arguments to the compiler.  MSYS tries to be smart and converts absolute
paths to native Windows paths.  But we want the paths as we compute them in
the Makefile.

This commit adds a workaround by replacing "/" with its octal
representation "\057", effectively hiding the path from MSYS.  MSYS does no
longer see the absolute path and therefore leaves it alone.
