This is odd behavior, but just annoying.
If I create a pch this way:
%COMP.sh "-x c++-header -Winvalid-pch" ostream
I get:
ostream:43:13: warning: #pragma system_header ignored outside include file
However, if I create a pch by doing
cat > precomp_ostream.hh
#include <ostream>
I don't get the error.
These cases, which are identical input, should give identical output.
