Compilation error when compiling php extension

Question

I'm following this tutorial to build a hello-world type extension for php, and compiling with visual studio 2008 express on Windows7. When I build, I get these errors:

1 has to do with allocation a constant array of size 0
the others seem to have to do with time.

But I'm not sure what they mean fully or how to fix them.

Compiling...

if you look at those lines in the files, then at the definition of STATIC_ASSERT,those are actually STATIC_ASSERT fails, checking that standard type names match the size specific 32 bit type names. seems to me you have a mismatch between 32 bit and 64 bit compiles somehow.

the business with cannot allocate an array of size 0 is a trick used in the static assert macro. not very informative.
