Ok, so I built make-3.81rc1 and still experience make not stopping upon errors.

Details are below.  The main excerpt:

$ make main.exe
-- generating makefile: main.d
main.cpp:1:21: sys/msg.h: No such file or directory
g++ -c  main.cpp -o main.o
main.cpp:1:21: sys/msg.h: No such file or directory
make: *** [main.o] Error 1

Note that the first error should stop the make, but it doesn't.

Notice that it works as I prefer it to via cygwin (details below).  Also 
note that cygwin has sys/msg.h, and mingw does not (and that's how I caught 
the problem in mingw, and noticed I was getting errors in the make output 
but the process was not stopping).

Do the make developers/assisters/moderators have enough info with this post 
to try and further analyze the problem?
