Actually, make invokes a shell if it detects any metacharacters on the
commandline. We need to take a look at that sh_chars_sh or whatever it's
called variable and verify whether or not it includes backslash and why.
FWIW, you can work-around it by appending "| cat" to the end of the command
line. That forces make to invoke bash:
[EMAIL PROTECTED] /tmp> cat mf
PROGS=foo
INSTBINDIR=./bin
CP = \cp
install: $(PROGS)
$(CP) $(PROGS) $(INSTBINDIR)
[EMAIL PROTECTED] /tmp> diff -u mf mf2
