make3.81-beta4 mingw not failing on error?

[Matt England]

Preliminary results in complex (but not all) conditions show that 
make3.81-beta4 compiled under mingw does not always stop when experiencing 
an error while executing commands in a rule.

I can provide more details tomorrow (after I get some sleep), but I thought 
I would ask about this in a preliminary fashion in case this was a known 
problem--and I could therefore possibly save myself some time on the 
analysis if so.

Thanks for any help,
-Matt
