It is not just in -CURRENT.  I just had the same problem after doing a
portupgrade of xemacs on my 4.9-RELEASE system.

Put the attached patch file in the editors/xemacs/files directory. 
The bug is that src/mem-limits.h is patched by the port to declare
the variable "lim_data" as type rlim_t (which is a 64-bit number) but
emacs.c still defines it as an int.  I am going to submit a PR.
