gdb not working properly in windows

I created a simple cpp file and compiled it using the cygwin g++ compiler in Win7. I am now trying to debug the resulting executable in gdb, but I can't get it to behave the way I expect it to. I cannot place breakpoints because when I try to execute b file.cpp:25 I get back 

No source file named file.cpp.
Make breakpoint pending on future shared library load? (y or [n])

I select y and it still does not break at the expected point. I did compile from this source.

I am getting a segfault at a certain point and whe also does not actually show line numbers. It seems to show memory addresses, which is obviously not useful to me.

Is gdb is misbehaving or am i just expecting it to do things it can't do? If it doesn't have this capability (though I've done this kind of thing before), is there another tool I can use?

In order to add debug information during compilation you should use the -g flag for g++.
