Apparently, though unproven, at 23:24 on Monday 11 October 2010, Daniel 
Pielmeier did opine thusly:

It's none of those apparently. I checked CFLAGS set by the ebuild in the 
emerge log before posting and they looked fine. gcc was last updated a month 
ago and the machine gets updated almost daily. 

glibc seems possible but it's a moot point, especially as after investigating 
memory at Mark's suggestion, genlop runs fine now, world updates successfully 
and 2 ./configure errors about aclocal (that I didn't even mention before) 
have gone away.

I should probably start treating this poor machine more like a notebook and 
less like a high performance machine - running flat out almost 24/7 is 
probably outside of it's design spec :-)
