that could indicate a bug in the configure.ac code for X detection.

yes. it is probably swapping itself to death. 

I can build kaffe's copy of classpath (which adds a ton of more files, 
including gnu crypto) on a box with 1gb in less then a minute (p4 3ghz, 
latest cygwin, win xp, etc.). 

Jikes is not superbly memory efficient. Afair, neither is gcjx or ecj.
Building Kaffe's copy of the class libs takes more than 180M of memory,
so (since I've got a p3-650/192M notebook :) I am building on more
potent machines.
