Erm, I was wrong.  :-/

Dan added multiline *output variable* support to CVS Autoconf, but not
multiline *cache variable*.  So, in fact, we are misusing caching here;
it's documented not to allow newlines.  Sorry for not clearing that up
back then.

Would you like to fix it?  You could either rewrite your first real awk
script to consist of one line only, or add a helper variable to remember
to unset lt_cv_sys_global_symbol_pipe after the AC_CACHE_CHECK, I guess.
(Please don't break caching for everyone else, it's a rather expensive
check.)

I would've guessed they'd chime in (and correct me ;-).

Cheers,
