Hello, Karthik.

I'm not sure what values are meaningful for make and how -1 is
interpreted: the argument of exit(3) seems to be (signed int), but bash
returns something like (unsigned char), where values 126, 127 and
128-... have special meanings, which yields codes 0 - 125 for use.

On my Debian GNU/Linux 3.0 system make doesn't proceed to the next
command. "info make" states the following:

"If there is an error (the exit status is nonzero), `make' gives up on
the current rule, and perhaps on all rules."

I can't see in which circumstances make gives up on all rules, but what
I see is that it should abort the execution of the current rule on any
non-zero exit status.


Hope this helps,
Baurjan.
