The problem is that the configure script merely warns you if it can't
find flex, but the Makefile assumes you have it, and is set up so that
if you don't, you end up with a 0-length lexer.c file instead of an
error, and then it keeps trying to compile and bombs out in the link
stage because the things that should be in lexer.c aren't.

Actually, maybe the bug is that the "lexer.c that comes with the
official distribution" that libIDL's configure script talks about
isn't actually there.
