Confirmed. Both are now fine.

If that option is passed, then configure sets a variable that gets put into config.h which main.c reads. If that option is not passed, then configure should try to find a suitable m4 and set the symbol as previously. The M4 environment variable is handy for certain situations that might arise as well.
