1.37 -which shouldn't be happening, he has no way to change a standard C++
1.38 -header. The warning is bogus anyway, but it's fixed in 4.1 through
1.39 -the CFG changes, which I don't really want to backport to the 4.0
1.40 -branch, so instead I'll add this patch. Other warnings generated from
1.41 -tree-inline.c check for DECL_SYSTEM_HEADER like this.

1.43 -Bootstrapped & tested on powerpc-darwin8, I'll commit when the branch
1.44 -is unfrozen.
