[PATCH v1] config.c: fix msvc compile error

[git@jeffhostetler.com]

From: Jeff Hostetler <jeffhost@microsoft.com>

In commit fb0dc3bac135e9f6243bd6d293e8c9293c73b9cd code was added
to builtin/config.c to define a new function and a forward declaration
for an array of unknown size.  This causes a compile error under MSVC.

Reorder the code to forward declare the function instead of the array.
