Did you ever actually *try* it?

##args.c##
#include <stdio.h>

main(int argc, char *argv[]){
       int i;
       for (i=0; i<argc; i++)
               printf("%s ", argv[i]);
       printf("\n");
}
#####

$ gcc -o args args.c
$ ./args foo bar -I/foo/bar
d:\Download\args.exe foo bar -IC:/msys/1.0/foo/bar

Of course there's no need for a /cygwin/<anything> with MSYS. Also 
there's no need to convert slashes to backslashes; Windows has accepted 
both since the Win95 days.  Likewise Windows accepts "-" as an option 
specifier as well as its old use of forward-slash.

Neither cccl nor wgcc *should* be setting the environment. That's what 
.profile is for. Or you could just edit msys.bat to call vcvars32.bat 
before starting up rxvt. It's not the job of the compiler-driver to set 
up the environment. It's the job of the *user* to do so.
