+- Fixed scs2pdf.c to handle very large spooled files.  We were
+    overflowing an array (textobjects).  This is now changed to be a
+    GArray.  Also changed some integers to unsigned long that counted
+    things like the number of pages.

 - Fixed NDEBUG support (again)
 - Applied patch from Marc-Antoine Ruel which fixes a bug in terminal.c
