Can you add -v and provide the output while invoking gcc like:
gcc -I./ -c -o main.o d1/main.c -v
This might be a mingw specific bug.
It works for me on linux on the trunk.

Sorry can't reproduce your issue. I tested it with 4.6 up to 4.8 gcc version
'gcc -c -o t.o subsub/t.c -I.' without issues.
I assume it might be caused that your working-directory isn't at TopDir, but in
SubDir on compilation of your code. You can verify that by adding -I.. as
option.

I find something interesting:
With -I. option, gcc works well.
With -I./ option, gcc fails.
gcc -v says:
ignoring nonexistent directory "./"
But even on Windows, both "." and "./" stand for "current directory", don't
they?

This error does exist on my environment.
And found more details.

testcase
It's funny that I just wanted to report almost identical issue. Can't believe
no one had encountered this before.
MinGW, GCC 4.7.0.
Attached test case is a bit different from author's original, yet similar:
"inc1.h: No such file or directory"
If you change one include path in makefile from -I./ to -I., everything
compiles without errors.
>From gcc -v with -I./:
#include "..." search starts here:
#include <...> search starts here:
./inc
d:\bin\mingw\bin\../lib/gcc/mingw32/4.7.0/include
d:\bin\mingw\bin\../lib/gcc/mingw32/4.7.0/../../../../include
d:\bin\mingw\bin\../lib/gcc/mingw32/4.7.0/include-fixed
And -I.:
#include "..." search starts here:
#include <...> search starts here:
./inc
.
d:\bin\mingw\bin\../lib/gcc/mingw32/4.7.0/include
d:\bin\mingw\bin\../lib/gcc/mingw32/4.7.0/../../../../include
d:\bin\mingw\bin\../lib/gcc/mingw32/4.7.0/include-fixed
***
Aaand on Linux with GCC 4.4.6 everything is fine. No errors.
-v -I./:
#include "..." search starts here:
#include <...> search starts here:
./inc/
./
/usr/local/include
/usr/lib/gcc/i686-redhat-linux/4.4.6/include
/usr/include
-v -I.:
#include "..." search starts here:
#include <...> search starts here:
./inc/
.
/usr/local/include
/usr/lib/gcc/i686-redhat-linux/4.4.6/include
/usr/include
***
So whom is to blame: GCC or MinGW?

--- Comment #8 from Kai Tietz <ktietz at gcc dot gnu.org> ---
That is a MinGW.org issue. For mingw-w64 this issue is fixed. Well, actually
it is under the hood a msvcrt issue about stat-routines. Sadly it can't handle
proper trailing slashes on paths.
To verify the issue simply check following test program:
#include <io.h>
#include <sys/stat.h>
#include <stdio.h>
int main()
{
struct stat fb;
if (stat ("./", &fb))
printf ("'./' stat failed.\n");
return 0;
}
I close this bug as invalid, due it isn't caused, nor to be fixed by gcc.
