[Bug middle-end/37902] New: [4.3 Regression] in_system_header bug

["jakub at gcc dot gnu dot org" <gcc-bugzilla at gcc dot gnu dot org>]

See http://gcc.gnu.org/ml/gcc-bugs/2008-10/msg01511.html

/* { dg-options "-O -W -Wall -Wdeclaration-after-statement -fpreprocessed" }

void
foo (void)
{
}

int
bar (void)
{
  return 0;
  int j;
  return j;
}

doesn't warn in bar, supposedly in_system_header hasn't been cleared when done
with foo function.

This is fixed on the trunk supposedly by
http://gcc.gnu.org/ml/gcc-patches/2008-07/msg01264.html
but that patch is definitely not backportable to 4.3 branch.
