Subject: poll (mingw): allow compiling with GCC 8 and DEVELOPER=1
X-Git-Tag: v2.23.0-rc0~72^2~3
X-Git-Url: https://granicus.if.org/sourcecode?a=commitdiff_plain;h=8d4679fe0995affd40301169fbfe6d679561bc64;p=git

poll (mingw): allow compiling with GCC 8 and DEVELOPER=1

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.
