>Description:
hello, world\n

It seems, make(1) doesn't understand substitutions in what the POSIX
standard calls internal variables ($@, $%, $?, $< and $*).
In the following example, the intent is to substitute any *.o in a *.c,
i.e. echo foo.c.

>How-To-Repeat:
$ cat Makefile                  
.POSIX:
foo.o:
        echo $(@F:.o=.c)
$ /usr/bin/make
echo foo.o.o=.c)
Syntax error: ")" unexpected
*** Error code 2

Stop in /usr/home/sje2bk.

GNU make works correctly, as well as Sun's /usr/ccs/bin/make:

$ /usr/local/bin/gmake
echo foo.c
foo.c
$                  


Is this a bug, a feature, lack of interest in POSIX conformance
or am I just confused? :-)
