[jamming] An option some of you may find useful...

[Peter Glasscock]

Some colleagues have been complaining that Jam continues to build
non-dependant targets when one fails.  I myself consider this a feature,
but they would like a way of stopping the build on the first error.

In response to this, I have made a tiny change to the Jam sources to
select this behaviour.  I am posting the change here, so that others who
might have had similar thoughts can use it.  You can also find the
change in my guest branch //guest/peter_glasscock, which also contains
some important fixes that haven't yet made it into the "official" Jam
sources.

If you think it's a useful feature, lobby Perforce to include this in
the "official" sources too.

Change 233:
edit //guest/peter_glasscock/jam/src/jam.c#5
edit //guest/peter_glasscock/jam/src/jam.h#3
edit //guest/peter_glasscock/jam/src/make1.c#5

Here is the change for those of you not familiar (or without) the p4
client software:

Cheers

Pete
