I have tried a lot of combinations of double double quotes '""', escaped double quotes '\"' and so on but I did not manage to get the file name passed as a single argument into my program.

It's a bug.  GDB handles the whitespace in a way that works on Posix
platforms, but not on Windows.

You can always use its 8+3 alias, something like mytest~1.txt (use the
"dir /x" command from the shell prompt to see the actual name),
instead of the long name.  This is a workaround, though.
