------- Comment #4 from tromey at gcc dot gnu dot org 2006-12-29 04:30 -------
I think this same problem will occur with #include_next
and #pragma once. cpp doesn't currently seem to differentiate between
the PCH case and other kinds of preprocessing.

c-family: Let libcpp know when the compilation is for a PCH [PR9471]
libcpp will generate diagnostics when it encounters things in the main file
that only belong in a header file, such as `#pragma once' or `#pragma GCC
system_header'. But sometimes the main file is a header file that is just
being compiled separately, e.g. to produce a C++ module or a PCH, in which
case such diagnostics should be suppressed. libcpp already has an interface
to request that, so make use of it in the C frontends to prevent libcpp
from
issuing unwanted diagnostics when compiling a PCH.
gcc/c-family/ChangeLog:
PR pch/9471
PR pch/47857
* c-opts.cc (c_common_post_options): Set cpp_opts->main_search
so libcpp knows it is compiling a header file separately.

Although the simplified testcase still works, note that with an installed compiler saying
g++ -x c++-header ostream
will say 'file not found' unless there is actually an ostream in the current directory.

Simple testcase:
testsys.h:
#pragma GCC system_header
g++ -ansi -Werror -pedantic -Winvalid-pch -o testsys.h.gch -c testsys.h
testsys.h:1:14: #pragma system_header ignored outside include file
