integer conversion warnings?

integer conversion warnings?

[Egon Eckert]

Hi,

is gcc/g++ able to warn me in these cases:

short int a;
long int b;
a = b;

that the conversion may lose significant digits?  Borland's
compiler does it and I would really appreciate that. :-)

I didn't find the answer in FAQs nor in list archives nor
with Google -- is it *so* obvious? :-O

Thanks,

I do not think so. Stay with Borland sofware..

I just tried  -Wall  which turns on almost all warnings, but
it didn't warn of the loss of precision.

My  lint  did, however.
