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

MSYS' automatic path conversion causes problems when passing paths as defines ('-D' arguments to the compiler). MSYS tries to be smart and converts absolute paths to native Windows paths, e.g. if MSYS sees "/bin" it converts it to "c:/msysgit/bin". But we want completely unmodified paths; e.g. if we set bindir in the Makefile to "/bin", the define BINDIR shall expand to "/bin". Conversion to absolute Windows path will takes place later, during runtime.

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