Here's a pretty significant bug I found in gnu make, version 3.48.

Given the following makefile, the third echo does not print what I
would expect.  It echoes "${SRC}".  I would expect it to echo "foo.o
fee.o".

By the way, I really like your program, and I think that you're doing
a fine service for the community.

--------
SRC = foo.c fee.c
SRC2 = ${SRC}

echo:
	echo ${SRC:.c=.o}
	echo ${SRC2}
	echo ${SRC2:.c=.o}
