Thanks for the patch and sorry for the long delay.

Unfortunately, such a change does not seem to be enough.  It will
let ./configure finish, however make will fail to compile 
filewith$dollar.c, because when the compiler is called as
   gcc -c -o filewith$dollar.obj filewith$dollar.c
$dollar will be interpreted by the shell.

For this to work, we should quote these filenames properly in
the rule.  Although it is not impossible, it's not easy to do in
the current (CVS) code because there are cases where automake
puts filenames in shell variables which are expected to be
interpreted...

Before spending time on this I'd really like to know why you
need `$' for.
