The attached patch is necessary as if you set the environment variable M4 to "m4 --nesting-limit=2048", the regexp won't match as there is a '=' rather than a ' ' after nesting-limit.
BTW if even 2048 is too small what could be wrong with my configure script? (In fact this is apr, at the autoheader stage) Cheers, Patrick
