Re: Lots of compile errors after recent source pull


That would probably be because I enabled the warning for
"-Wmismatched-tags" on clang/GCC. This shouldn't be an error though, only a
warning. It warns about declaring things class/struct inconsistently (on
MSVC builds this can cause problems, so I enabled this warning to ensure we
don't have issues with this since we are starting to have more people
use MSVC). It appears that the system headers in GCC don't follow that
standard unfortunately, but usually warnings from inside system headers are
ignored (apparently on the C++ headers on my machine it is also mismatched
but I don't see all the warnings when building with Clang). These are
supposed to be hidden when the include directories are system include
directories though.

Do you see this for other headers, or is it just this one header? I
wouldn't mind forwarding this upstream to cleanup their headers.
