Virtual Estates, Inc.
>Environment:
7.x or 8.x system, where gcc-4.2 is the system compiler
>Description:
The following bug prevents ANY C++ code from being built with WARNS set
to anything, because -Wsystem-headers is included even when WARNS=1 (see
share/mk/bsd.sys.mk):
In file included from /usr/include/c++/4.2/ios:50,
from /usr/include/c++/4.2/ostream:45,
from /usr/include/c++/4.2/iostream:45,
...
/usr/include/c++/4.2/bits/basic_ios.h: In member function 'void std::basic_ios<_CharT, _Traits>::_M_setstate(std::_Ios_Iostate)':
/usr/include/c++/4.2/bits/basic_ios.h:156: warning: empty body in an if-statement
>How-To-Repeat:
One example would be to build /usr/ports/graphics/libfpx/
>Fix:
Explicitly set NO_WERROR, as is currently done in 7.x. This defeats the
main purpose of WARNS, however...
