Currently, using an undeclared function gives a compile warning, but it
can lead to a nasty runtime error if the prototype of the function is
different from what gcc guessed.
With -Werror-implicit-function-declaration, we are getting an immediate
compile error instead.
There will be some compile errors in cases where compilation previously
worked because the undefined function wasn't called due to gcc dead code
elimination, but in these cases a proper fix doesnt harm.
This patch also removes some unneeded spaces between two tabs in the
following line.
