Issue in src/xfns.c

[Christian Lynbech]

I am not entirely sure what the intention was, but I think there is a
small issue in xfns.c in relation to the RANDR13_LIBRARY macro.

It is used in two places, one where it uses #if and another that uses
#ifdef, the latter of which I think should have been a #if. At least it
failed to compile for me on a rather old linux system with a setup I
know onbly a little about. The define that introduces RANDR13_LIBRARY is
a boolean expression so RANDR13_LIBRARY is always defined.

As far as I can see this is still present in the git repository on the
master branch. An attempt of a patch is given below.
