On the command line the space separates it into two arguments.  The
options-file way to do this would be to put each on its own line:

-I
C:\Program Files\Faked Path\With\include
-I
C:\Foo\Bar\Foo\Bar\Foo\Bar\Foo\Bar\2.0.7\include\Common
-I
C:\Bar\Foo\Bar\Foo\Bar\Foo\dev\include
-I
c:\Bar\Bar\Foo\Foo\Bar\Bar\Foo\Foo\runtimetest
-I
c:\Foo\Foo\Bar\Bar\Foo\Foo\dev

This approach makes the options file trivial to parse and its syntax
easy to define.  There is no need for any escaping or quoting.

The windows command line limit is just under 32K.  I'm not aware of a
particular limit in gccxml though.  Can you reproduce this and post
instructions?
