Comment:

 Replying to [comment:2 maeder]:
 > The $(SHELL) setting from configure is not taken, because
 mk/config.mk.in contains /bin/sh hard-coded.
 > A fix might be:

 > {{{
 > -SHELL                  = /bin/sh
 > +SHELL                  = @SHELL@
 > }}}

 I propose to commit this change in line 655 of mk/config.mk.in as it is
 still relevant for me and ghc-7.8.1-rc2. Could someone do this?
