commit 3d4f101e7b74dc7df9a98186bfdd283851e34797
Author: G. Branden Robinson <[email protected]>

[libgroff]: Slim library on non-Windows systems.
* src/libs/libgroff/relocate.cpp (searchpathext): Declare as `static`
since it does not require external linkage. Doing so reveals that the
function is not used at all except on Windows systems, so bracket with
preprocessor `#ifdef`/`#endif`, avoiding `-Wunused-function` warning
from GCC on GNU/Linux.
