I think there is a bug in make, but it could just be my bad usage. 

Can someone please say if the test makefiles below should work ok with
the DJGPP port.

The bug appears in the DJGPP ports 3.77 and 3.78.1, but not 3.77
running under Linux.

To demonstrate, there are 3 makefiles and 2 sub-directories:

-------- makefile --------
all:
	cd sub1; make
	cd sub2; make

-------- sub1\makefile --------
test1:
	touch test1

-------- sub2\makefile --------
test2:
	touch test2


Here's what happens when make is run:

D:\Tmp>make
cd sub1; make
make.exe[1]: Entering directory `d:/tmp/sub1'
touch test1
make.exe[1]: Leaving directory `d:/tmp/sub1'
cd sub2; make
make.exe: *** [all] Error -1


The problem does not exist if make recursion is done correctly:

-------- makefile --------
all:
	$(MAKE) -C sub1
	$(MAKE) -C sub2

D:\Tmp>make
d:/djgpp/bin/make.exe -C sub1
make.exe[1]: Entering directory `d:/tmp/sub1'
touch test1
make.exe[1]: Leaving directory `d:/tmp/sub1'
d:/djgpp/bin/make.exe -C sub2
make.exe[1]: Entering directory `d:/tmp/sub2'
touch test2
make.exe[1]: Leaving directory `d:/tmp/sub2'
