Re: [Patch 4.6] In system.h, wrap include of C++ header in 'extern C++'

[Duncan Sands]

Hi Richard,

As system.h is supposed to only include system headers and do nothing
else it has to be prepared to be included from C++ already, so no extern "C"
wrapping should be necessary for it.

it defines fancy_abort.  Not wrapping system.h in extern C results in
  undefined symbol: _Z11fancy_abortPKciS0_
when loading the plugin.

Ciao, Duncan.
