Fix builds of Xnest & Xephyr 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 errors: "Display.c", line 65: Function has no return statement : x_io_error_handler "hostx.c", line 341: Function has no return statement : x_io_error_handler 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.
