Hi
sparc64*-*-rtems* ends up with __svr4__ defined. The attached
patch corrects that.
OK to apply?
013-05-10 Joel Sherrill <joel.sherr...@oarcorp.com>
* config.gcc (sparc64*-*-rtems*): Use sp64-rtemself.h.
RTEMS target should not have -D__svr4__ in CPP_SUBTARGET_SPEC.
* config/sparc/sp64-rtemself.h: New file.
