[PATCH 1/4] poll (mingw): allow compiling with GCC 8 and DEVELOPER=1

[Johannes Schindelin via GitGitGadget]

From: Johannes Schindelin <johannes.schinde...@gmx.de>

The return type of the `GetProcAddress()` function is `FARPROC` which
evaluates to `long long int (*)()`, i.e. it cannot be cast to the
correct function signature by GCC 8.

To work around that, we first cast to `void *` and go on with our merry
lives.
