Symptom: Setting R_SHELL=/bin/bash causes make to fail.

Reproduce with:
bash-3.00# export R_SHELL=/bin/csh;./configure --with-readline=no
--with-iconv=no --with-x=no --enable-static=yes 
--prefix=/home/dev/scratch/bbownes/R
bash-3.00# make
Badly placed ()'s

if test ! -f "./doc/FAQ" || test -f non-tarball ; then \
  (cd doc/manual && make front-matter html-non-svn) ; \
  touch non-tarball ; \
  (cd .; LC_ALL=C TZ=GMT svn info || echo "Revision: unknown") 2> /dev/null \
    | sed -n -e '/^Revision/p' -e '/^Last Changed Date/'p \

  if test "yes" = no ; then \
    for f in SVN-REVISION; do \

Was the intention of R_SHELL to allow you to set a path to your own version of
csh?
