Fix builds of scope.c with Solaris Studio compilers
Required in order to build with Studio cc now that xorg-macros is setting -errwarn=E_FUNC_HAS_NO_RETURN_STMT since a bug in the Solaris system headers causes the noreturn attribute to not be correctly applied to the exit() prototype in <stdlib.h> when building with Studio instead of gcc. Otherwise compiler exits with error: "scope.c", line 643: Function has no return statement : CMDQuit Uses Studio-specific pragma instead of adding another exit() prototype with a noreturn attribute to avoid causing gcc to warn about having a redundant prototype for the exit() function.
