C++ extension question

I developing some extension on m$ platform with M$VC6.0 ( it's a OpenSSL crypto capabilities, more advanced than OpenSSL extension providing, when i fill it ready i will try to publish to PHP site) when core language for internals is a C++, meaning inside implementation of PHP functions there calls to C++ classes; may be in future i should actually use PHP object oriented side. Until than was not much functions it was nice and exciting development , until number of functions grow to more than 60 and becomes a little hard to maintain in one file. I tried to do very standard thing , segregate functions by they functionality to different files , and all seemed to be happy in compilation but not in linking; I'm receiving this php_TPKCS12.obj : LNK2005 error: _delete already defined in cert.obj php_TPKCS12.obj : warning LNK4006: _delete already defined in cert.obj; second definition ignored I searched forums of PHP and around for some examples of somebody stuck with same problem , but haven't found something similar; There some references and even explanations how to create PHP extension in C++ but there again considering that all PHP functions are defined and implemented in one file. obliviously this is very urgent and not very "hot" issue , but still could somebody give a look on this . Not interesting proposition like search for C function named "delete" is not counting. There is no such thing in PHP code and not in my code My hint (and after some digging in code, another point to have open source code for applications) that somewhere in ZEND engine there definition that confusing compiler/linker that not protected from header file redefinition problems ...
