yes, also a nice idea :)

so the users that do not fix warnings during normal compilation
do not `forget' to run make warnings and then fix all the errors?

I would guess the users that forget to fix warnings are the same
that forget to run `make warning' :)

Isn't there a generic way? Configure has some `checking whether
we are using the gcc compiler', right?
So why not adding some `checking whether we are using the MS
 (we have some if test $CC=CL.EXE check, but better would to run
 it and check the output text / version number to find out what
 it is, also to support options that have been renamed across the
 versions / years)
