AC_OUTPUT vs m4 nesting limit

[Andreas Schwab]

When trying to generate more than 250 files with one configure script
(like the kdebase package wants to do) you'll hit the nesting limit of m4
(due to the fact that loops are implemented through recursion).  Currently
there is no way increase this limit from the autoconf invocation.  How
about adding an option so that, say, --m4-options=--nesting-limit=300 can
fix that?  Or maybe this limit should be increased by default?

Andreas.
