Of course, I thought that was self-evident so I didn't remark on it.
The issue is that make _should_ process the @ and does if the case is
simplified any further.

Good point, I didn't do that.  The output is:

make SHELL=~/bin/echo-bash -f make-define-bug.mk

  @echo hi
+ bash -c '@echo hi'
bash: line 1: @echo: command not found
make: *** [a] Error 127

I'm not sure what I was supposed to see.  I know the @ is being passed
to the shell.  Or did I miss something?

Yes, that's what I think.  But I suspect it is specific to cygwin, the
same makefile works fine on our local GNU/Linux box.

Thanks for looking into it.  As always cygwin rules!

Cheers,
