Something changed within the last day or two, causing the number of
spill locations (mcs51 large model) to massively increase... from a few
dozen bytes in my mp3 player project, to many hundreds.... much more
than the internal RAM of the 8051.
Sorry to be so vauge... I'll try to get some recent checkouts and see
what caused it, but I wanted to post something right away, as this many
spill locations makes SDCC unusable for any sizable project.
