I hit some problems compiling a C++ extension in a non-threaded environment, because of some missing extern "C" declarations. Looks like this was previously fixed for threaded mode only. Please would someone with karma apply the following patch?

What about ini_scanner_globals & language_scanner_globals? Don't they require the same declaration?

I think it's almost certain that they do - I just didn't have a test for them, so I used the "if it ain't broke don't fix it" principle.

Also, how to reproduce it? I compile C++ extensions quite often and do not see any problems.

Well you need to have an extension which references CG() or EG() from C++ and build it with --disable-zts. So, compiling the sdo extension, which refers to, for example, EG(uninitialized_zval_ptr), the link step gives: SDO_DataObject.obj : error LNK2001: unresolved external symbol "__declspec(dllimport) struct _zend_executor_globals executor_globals" (__imp_?executor_globals@@3U_zend_executor_globals@@A) Debug\php_sdo.dll : fatal error LNK1120: 1 unresolved externals because the references are getting mangled. Putting them inside extern "C" fixes this. (my example was obviously on Windows, but the same should apply on *IX)
