NULL is defined as 0 in dll.e, and it is *not*
a valid argument type. I suspect what the author
meant to say here was:

WINVER = link_c_func2(edx, "WINDOWS_VERSION", {}, C_UINT)

i.e. that the C function WINDOWS_VERSION takes no arguments
and returns a C_UINT as a result.

Later in the code, when he calls WINDOWS_VERSION,
he probably passes it a dummy argument. You'll have to
remove that dummy argument from each call to WINDOWS_VERSION.

I guess the author just didn't realize that he should
define a function of no arguments by using {} rather than {NULL}.
Apparently this worked without crashing, so he didn't
have to correct it in 2.3.
