How shall this work?  FT_Init_FreeType needs an argument, but you are
faking it with an incorrect declaration.  The above test (probably
taken from an autoconf snippet) can be *only* used to test whether the
function `FT_Init_FreeType' is available in the library to be checked
for.  It is *not* meant to ever get a working executable.
