Thank you very much for your insights, Ron. I thought you'd nailed it with
that, but actually setting .SHELLFLAGS seems to make no difference. That
maybe a bug in make 3.81 (which is the current version on riscos.info), as
reported here:
http://lists.gnu.org/archive/html/help-make/2012-10/msg00014.html

I don't really understand how the SHELL variable works for the RISC OS
port of make. As Ron says, and according to the manual, the default value
of SHELL is "/bin/sh", which makes no sense on RISC OS. Does the port in
fact just direct commands at the RISC OS command line unless SHELL is set
to something else?

I did install the port of bash and added "SHELL = bash" to the Makefile,
and then it works, but only if I substitute "echo" for "printf" - "printf"
obviously isn't a bash command.

I'd ideally like to use the RISC OS command line as the shell, not bash,
but this "-c" issue is flummoxing me.

If anyone else can confirm the .SHELLFLAGS issue is peculiar to make 3.81,
that would be great.

Many thanks for any help,

WPB
