[BUG] Compilation fails on current master branch

results in:

What compiler are you using?

[hsutter]

@userxfce Thanks! You must be compiling with gcc or Clang with -Wall -Wextra plus turning warnings into errors with -Werror, which should be fine but this week I added some code that triggers the above warning.

Fixed by the commit above, it now compiles cleanly again under -Wall -Wextra.

@filipsajdak fixed already, but for reference:
