OK, I see now: you're treating 'make all' as a special case
by testing for 'all' in $(MAKECMDGOALS), and likewise for
the two '.exe' targets.
First, let's try MSYS's own 'make' in its own 'bash':
/c/tmp/me_make-test[0]$ls
Makefile alt1.cpp main.cpp
/c/tmp/me_make-test[0]$/c/msys/1.0/bin/make main.exe
-- generating makefile: main.d
set -e; rm -f main.d; \
echo "# DO NOT CHANGE THIS FILE; it was auto-generated by a make
process." > main.d; \
g++ -M main.cpp > main.d.2608; \
sed 's,^.*\.o[ :]*,main.o main.d: ,g' < main.d.2608 >> main.d; \
rm -f main.d.2608
main.cpp:1:21: sys/msg.h: No such file or directory
make: *** [main.d] Error 1
/c/tmp/me_make-test[2]$ls
Makefile alt1.cpp main.cpp main.d main.d.2608
/c/tmp/me_make-test[0]$cat main.d
# DO NOT CHANGE THIS FILE; it was auto-generated by a make process.
Neither the 'sed' nor the last 'rm' command was executed,
and 'make' stopped right there, which is what you want.
Now let's try the release candidate:
/c/tmp/me_make-test[0]$ls
Makefile alt1.cpp main.cpp
/c/tmp/me_make-test[0]$../make-3.81beta4/make main.exe
-- generating makefile: main.d
set -e; rm -f main.d; \
echo "# DO NOT CHANGE THIS FILE; it was auto-generated by a make
process." > main.d; \
g++ -M main.cpp > main.d.3760; \
sed 's,^.*\.o[ :]*,main.o main.d: ,g' < main.d.3760 >> main.d; \
rm -f main.d.3760
main.cpp:1:21: sys/msg.h: No such file or directory
g++ -c main.cpp -o main.o
main.cpp:1:21: sys/msg.h: No such file or directory
make: *** [main.o] Error 1
/c/tmp/me_make-test[2]$ls
Makefile alt1.cpp main.cpp main.d main.d.3760
This time, 'make' didn't stop where expected: it proceeded
to attempt 'g++ -c main.cpp -o main.o'. I think that's the
problem you're reporting.
Now let's try the same thing in a native msw port of zsh:
C:/tmp/me_make-test[0]$path=(/MinGW-20050120/bin/ /usr/bin/ /usr/local/bin/)
First, the old make I've been using for so many years that
I don't remember where it came from. This zsh port doesn't
seem to understand $(PID), so I'll force it to 9999.
C:/tmp/me_make-test[0]$ls
Makefile alt1.cpp main.cpp make-test.tar.gz
C:/tmp/me_make-test[0]$make main.exe PID=9999
-- generating makefile: main.d
set -e; rm -f main.d; \
echo "# DO NOT CHANGE THIS FILE; it was auto-generated by a make
process." > mai
n.d; \
g++ -M main.cpp > main.d.9999; \
sed 's,^.*\.o[ :]*,main.o main.d: ,g' < main.d.9999 >> main.d; \
rm -f main.d.9999
main.cpp:1:21: sys/msg.h: No such file or directory
\usr\bin\\make.EXE: *** [main.d] Error 1
'make' stopped on the failing command. FWIW:

Now the release candidate:

C:/tmp/me_make-test[0]$../make-3.81beta4/make main.exe PID=9999

rm -f main.d.9999
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.EXE: *** [main.o] Error 1
C:/tmp/me_make-test[2]$
Here, 'make' proceeded past the first failing command.
So it looks like the problem can be reproduced without
using MSYS's bash--instead using a non-MSYS zsh and
an MSYS-built 'make' beta.
Here's some debug output with the release candidate:
CreateProcess(C:\usr\bin\sh.exe,/usr/bin/sh.exe -c "set -e; rm -f main.d;
\
echo \"# DO NOT CHANGE THIS FILE; it was auto-generated by a make
process.\" > m
ain.d; \
g++ -M main.cpp > main.d.9999; \
sed 's,^.*\.o[ :]*,main.o main.d: ,g' < main.d.9999 >> main.d; \
rm -f main.d.9999",...)

So where the release candidate says
Reaping losing child 0x00c22100 PID 12722752
Removing child 0x00c22100 PID 12722752 from chain.
the old version of 'make' says

\usr\bin\\make.EXE: *** [main.d] Error 1
Removing child 0x003de110 PID 4057464 from chain.
