Exit value

[Oppermann, Henry]

As I understand it, when make invokes a process to handle a command and the
process ends, Make learns the exit value from the child process.  Is there a
way to gain access to this exit value?  I have a case where an assembler
returns a code which is valid for <= 4.  Above that value, I want to exit.
Make exits if the value is >0.

Limited to cmd.exe on Windows systems.

Thanks in advance,
