egcs-1.0.1 can't find headers in -I./

[Richard Hadsell]

It seems that egcs-1.0.1 does not recognize -I./ as the current
directory.  This was true of egcs-1.0 as well.  -I. works fine.  It
would be nice to get -I./ working, because we have some make rules that
generate the include path automatically from discovered header files,
and they give "./" as the directory for any header file that is named
without a path.

I think that this test case is telling us that it misinterprets "-I./"
as "-I/":
