Compiling under Borland C Builder / No BEGIN_EXTERN_C?

I've been working on a project which requires me to write a zend extension (http://capnbry.dyndns.org/phpub/), I've been using Visual Studio to do the work so far as this is targeted for the Win32 platform. I recently decided to move to Borland C++ Builder after I got fed up with the VC++ IDE. I had to tweak a couple of things in the header files to get it compiling, but the changes were minor (available upon request). The problem I came into was on the link, unresolved symbol errors on functions exported from php4ts.dll. Digging in I realized that the problem was because /some/ of the names of the functions I was importing (via ZEND_API, PHP_API, etc) were getting mangled because they were not enclosed in the BEGIN_EXTERN_C() / END_EXTERN_C() macros. Is this intentional, or is it just because no one has ever tried to use the headers from inside a .cpp file? Some of the functions of intrest are: main/php_main.h: php_request_startup() ... php_handle_auth_data() ext/standard/php_output.h php_output_startup() .. php_get_output_start_lineno() I've modified the header files to block the __declspec(dllimport) functions with BEGIN / END_EXTERN_C. If there is no reason to *not* have these in, may I submit a patch to allow the headers to be included in C++Builder and other C++ build environments? My C is rusty, so flame me if I'm wrong, Bry
