Summary: Problem with -I../../ when building/Multiple slash handling

Initial Comment:
Compiler seems to fail when attempting to add -I 
with ../../ or ../ to include files one or two dirs above.  
Same example works fine under Linux and Solaris.

Steps to recreate:

1) Untar the dir...
2) go down to the lowest dir where test.c is
3) type gcc -I../../ test.c

EXPECTED RESULT: Successful compile.
ACTUAL:
$ gcc -I../../ test.c
test.c:2:17: foo.h: No such file or directory
test.c: In function `main':
test.c:7: error: `ONE' undeclared (first use in this 
function)
test.c:7: error: (Each undeclared identifier is reported 
only once
test.c:7: error: for each function it appears in.)

I have some live examples of this happening.

However, when I do

gcc -I../.. test.c

Everything works.  This seems to imply that MinGW 
doesn't properly handle multiple slashes in a pathname, 
which is a critical bug, if it's going to offer a UNIX 
compatible build platform.
