Do you only want this to happen for executables?  What happens if you do 
"gcc -o foo.o foo.c"?

We can definitely create some cygwin-gcc wrapper scripts, and you can 
use the existing scripts in pkgsrc/mk/wrapper as a guide to writing 
them.  However, this particular transformation you're trying to do looks 
potentially hard because we need to figure out when we're linking an 
executable versus linking a shared library or compiling an object file.

I'll help out where I can.
