This got tossed around two years ago, and I think the
resolution was that you could change SEGMAPSIZE in pc/mem.h
and all would be fine. The two attached messages contain
the necessary bits I think.
Nigel Roles said once that 8l uses 20MB to link ghostscript
without any printer drivers.

I hate replying to my own mail, but I guess I wasn't finished... :-)

Make that SEGMAPSIZE.
Also several of the machines have this in mem.h:
#define SEGMAPSIZE 64 /* 16 is for wooses */
This would imply that all is necessary is to change 16 to 64 in pc/mem.h,
but that would be too simple...
Thanks again.

changing SEGMAPSIZE works fine.
It incurs overhead allocated Segment structures
so 16 seemed reasonable for a terminal. We really
dont use PC's to compile.
