I read through the man page for GNU make and it looks to me like the following two lines should be equivalent.

c1 $ gmake A=B -j 4
c2 $ gmake -j 4 A=B

However, apparently c2 limits itself to 4 parallel jobs while c1 is equivalent to -j without arguments and spawns a limitless number of jobs.

Additionally, I would like to request that -j without arguments default to something more reasonable than -j infinity. I have seen novice users just throw -j without arguments on to the command line hoping for a speedier build only to irritate other people on the build machine when every process on the system crawls to a halt. I think -j without arguments should mean -j 1 or -j 2.
