Description Christian Helmuth 2005-10-07 10:59:13 UTC 
// gcc 3.4.5 and 4.0.2 produce warning output 
#define STATIC

// no warning
#define STATIC static

STATIC int foo(void)
{
  int i = 47;
  i++;
}

int bar(void)
{
  if (foo()) return 1;
  return 0;
}
Comment 1 Andrew Pinski 2005-10-07 11:12:01 UTC 
Fixed in 4.1.0 by change a lot of the middle-end so the patch will not be backported, so closing as fixed.  There is most likely a dup of this bug somewhere.

	PR bootstrap/24252

	* Makefile.def (flags_to_pass): Add STAGE1_CFLAGS and STAGE1_LANGUAGES.
	* Makefile.tpl (OBJDUMP): New.
	(EXTRA_HOST_FLAGS): Add it.
	(EXTRA_GCC_FLAGS): Remove flags already specified in flags_to_pass.

        * Makefile.tpl (stage[+id+]-start, stage[+id+]-end): Do not try
        to use symbolic links between directories.  Avoid race conditions
        or make them harmless.
        * configure.in: Do not try to use symbolic links between directories.

	* Makefile.def (LEAN): Pass.
	* Makefile.tpl (LEAN): Define.
	(stage[+id+]-start): Accept that the previous directory does not
	exist, if the bootstrap is lean.
	(stage[+id+]-bubble): Invoke lean bootstrap commands after
	stage[+id+]-start.  Use a makefile variable and an `if' instead of a
	configure substitution.
	([+compare-target+]): Likewise.
	([+bootstrap-target+]-lean): New.
	* configure.in: Remove lean bootstrap support from here.

        * Makefile.in: Regenerate.
        * configure: Regenerate.
