how to increase the maximum number of pages in gcl?

Hi,

I'm running a big messy job, and run out of memory quickly.  (Allocate 
'cons really-big-number) doesn't help, because there just aren't enough 
pages to go 'round.  I've tried setting *ignore-maximum-pages* to true, 
but that doen't seem to produce any effect.  (Room) produces the 
following output at the beginning of a job:


[tomlinso@desktop gcl-2.4.0]$ maxima

  378 pages for cells
  556 total pages
30069 pages available
2143 pages in heap but not gc'd + pages needed for gc marking
32768 maximum pages
MAXIMA>>

That 32768 maximum pages seems to work out to about 128M, and  I may 
well need four times that.  I'm running this on a machine with 512M of 
ram and tons of swap space, and buying more ram isn't out of the 
question, so it makes sense to have a really big maximum pages. 

Is there an argument on the command line when I run gcl, or is there 
something I can edit in the config or makefile, which will give me some 
extra room?

Thanks,
