This works under SunOS 4.0.3 (and probably others):

	system("/bin/csh -c \"<command>\"");

system() calls /bin/sh, which in this case starts a `csh' to perform
<command>.  Note the \" around <command>.  Here is a quick example:

main()
{
	system("/bin/csh -c \"/bin/echo This command run by /bin/csh !\"");
	exit(0);
}
