Given the Python situation, I wouldn't be totally suprised if it didn't.
But I still don't really understand why.

The mingw compiler should be capable of producing code with the same
calling conventions - after all mingw is built on the idea of using
the Microsoft C runtime DLL, and it can work with other DLLs too - it's
not just some hand crafted assembler glue specific to the CRT DLL.

I can believe you can't link C++ code from both mingw and Microsoft
toolchains, since the C++ libraries aren't compatible.  Even if you
don't use the libraries, the C++ name mangling and exception handling
may not be the same.  But Xapian's C++ code is hidden in DLLs behind a C
API from PHP's point of view, so this shouldn't really be a problem.

"If you have Microsoft Visual Studio, you can also build PHP from the
original source code."

Which seems to suggest you can't build it with mingw.
