I'd like to get warnings on loss of data during implicit conversions

When i compile my c or C++ code under Microsoft compiler I get warnings like the following:
warning C4244: 'argument' : conversion from 'unsigned long' to 'uint16
', possible loss of data

However, compiling the same code with Gcc/G++ does not produce this warning at all?

My question is:
- is this a standard (i mean ISO) warning? or is it a courtesy warning?
- Does gcc have something similar to this? If so which option is that?

I have tried the following individiaully and in combination to no avail:

-Wall, -Wextra, -Wconversion
thanks
