Here an example that the test
if test "$SRCDIR" = "$DSTDIR" ; then
{ echo "configure: error: *** Build directory should not be the same as source \
can fail:
SRCDIR: /hardmnt/thuille1/ssi/cvsgrass_exp
DSTDIR: /ssi0/ssi/neteler/cvsgrass_exp
The situation is that I have changed into the source code
/ssi0/ssi/neteler/cvsgrass_exp/ directory via soft-link:
cd /ssi0/ssi/neteler/cvsgrass_exp/
thuille:cvsgrass_exp[304.48] pwd
/ssi0/ssi/neteler/cvsgrass_exp
thuille:cvsgrass_exp[305.49] /bin/pwd
/hardmnt/thuille1/ssi/cvsgrass_exp
Personally I enjoy that it fails as I can launch 'make' as
usual

Right. I appear to have been distracted by the fact that one of the
three cases uses $pwd (which will be set to "/bin/pwd"); however, the
other two just use "pwd" which will be the shell's built-in:
AC_PATH_PROG(pwd, pwd, pwd)
AC_MSG_CHECKING(for source directory)
if test -z "$srcdir" ; then
SRCDIR=`pwd`
else
SRCDIR=`(cd "$srcdir" ; $pwd)`
fi
AC_MSG_RESULT("$SRCDIR")
AC_MSG_CHECKING(for build directory)
DSTDIR=`pwd`
AC_MSG_RESULT("$DSTDIR")
For the $SRCDIR = $DSTDIR check to work correctly, we need to use $pwd
in all three cases. I'll fix this.
