Comment (by Erik Schnetter):

 I've changed the variable from {{{unsigned long}}} to {{{long}}}.

 I have not changed the error tests to check against {{{-1}}}, since all
 negative values indicate errors, in the sense that our
 {{{malloc(filesize)}}} later on will fail for any negative file size,
 independent of whether the file size is {{{-1}}} indicating an error in
 {{{ftell}}}, or whether {{{ftell}}} returns another negative number for
 some other reason.
