Thanks to Richard for the config patch for lesstif.
I had to apply it by hand, as patch config.guess config.guess.patch
didn't work (can't remember the reason). 'make' then trundled happily 
away for a bit, got further than on the last attempt, and then stopped 
with errors about no space left on device.
Initially, I expected I'd run out of swap, but systat showed only 20% 
used. / is 74% used however, and I created it as 32MB (I think) as 
suggested in the install guide. Should I have made it bigger?

Finally, ISTR many months ago, somebody mentioned 'unlimit' to allow the 
compiler to use all swap space. How do I use that?

Here are my errors:

1%cd /usr/X11R6.3/install/lesstif-0.81
2%make
