To answer Magnus' question in that thread, the Mingw headers on jacana
declare the function with WINBASEAPI which in turn is defined as
DECLSPEC_IMPORT, as long as _KERNEL32_ isn't defined, and we don't do
that (and I don't think anything else does either).
So the fix Peter proposed looks like it should be correct.
