This returns the previous behavior as default and allows more flexibility.

Hi,
current cvs (14.4.2000 7:00 GMT) fails due to
gcc -c -I. -DHAVE_CONFIG_H -O3 -fstrict-aliasing -o builtin.o builtin.c
In file included from zsh.mdh:32,
from builtin.c:30:
jobs.epro:8: `MAXJOB' undeclared here (not in a function)
builtin.c: In function `checkjobs':
builtin.c:3159: `MAXJOB' undeclared (first use in this function)
What's gone wrong?
Thanks,
Helmut.

Clint just made MAXJOB configurable, you need to re-run autoconf.
