Hi,
The following patch lets clisp build on alpha (sid) as per the bug
report 111285; I picked this bug up because it was marked 'help' and I
have an Alpha. However before today I've never done any lisp and thus
while it builds, seems to run and apparently does floating point square
roots I can't be sure it is triggering this code I'd be happy to try
some tests if you want.
More to the point I don't know why this is only triggered on Alpha; the
problem seems to be due to declearing the DS wurzel variable in the
middle of a block; but the macros seem to insert blocks automatically in
some places - but not this one (It opened a new block after the var DS
wurzel line).
I should at this point out that as well as not knowing lisp I also don't
know German and that Google's translation was very useful (if a little
amuzing).
Enjoy,
Dave
