I do not remember details. As you can see varables on '$fluidVars'
are declared special in Lisp output. However, sbcl signals error
when there are too many special declarations (and newer sbcl
versions got more picky). $dollarVars constains variables
with name starting from '$', which by Boot convention means
global variable. For such variables special declarations
are not necessary, and the change means that we no longer
emit such delarations. This in particular eliminated problem
due to extra special declarations.
