I have recently installed the GNU make facility 
on the 4.3BSD system at Perihelion Software and 
have experienced one (admittedly not very serious)
problem. viz. The following makefile which uses
a header file which has been found using vpath and
then goes on to name the same file but without the
vpath searching. This causes make to core dump!

vpath %.h tt

all: x.o y.o
x.o: x.h

y.o: tt/x.h

The problem appears to be concerned with rename_file
where it realises that there is a file with the target
name already and proceeds to free it. Unfortunately 
the freed pointer is then used later when trying to make
the file which was named absolutely. I realise that this
is not a major bug since one would not want to name files
in this way when using vpath but I thought you would be 
interested nonetheless.
