Thank you all for your replies.  I have c. 650M RAM and 1G swap.  I did not 
have a problem emerging gcc until this version.  How can I know if it runs out 
of memory, unless I continuously keep an eye on memory counts - is there a 
cleverer way to know this?

I tried emerging it with MAKEOPTS="-j1" and it failed again, but with a 
different error:

Does this point to anything more obvious, or shall I start running memory 
tests on this box?


PS.  STOP PRESS!  I just found this: 

     https://bugs.gentoo.org/show_bug.cgi?id=411333

This is a bug that affects only PIIIs.  Unsurprisingly, not many people still 
run them.  I'll try with CFLAGS=i686 to see if it completes.
