pango parse error before "XErrorEvent" on Solaris 2.7

[David Nedrow <listbox nedron net>]

I'm having trouble compiling pango on Solaris 7. It compiles fine if I 
disable X (via --without-x), but fails at several points with the error 
I've pasted below if I let it try to build pango with X support.

Here's one of the functions (around line 525 in pango/pangox-fontmap.c) 
that is causing a problem:

static int
ignore_error (Display *d, XErrorEvent *e)
{
  return 0;
}

I'm not sure what the issue is. Any ideas out there?
