This happens on certain Windows 95 machines (at least); Guido Masarotto and
I traced it to machines running Windows 95a (that is the original W95 with
service pack 1); machines running Windows 95b or c (OSR2 and OSR2.5) are
able to dyn.load.  We thought compiling under a later compiler (egcs 1.1) 
might help, but it does not (report to Guido: I tried this last week). 

The good news is that cross-compiling from Linux does seem to work: the
version Guido announced on R-announce yesterday of 0.62.3 does allow
dyn.load on the machines here that had problems with rw0613, and since it
has a much faster interface (and IMHO nicer interface) and is the current
0.62.3, I suggest you try that instead. It does have fewer libraries as
yet, but since you cannot use them with rw0613, that is no disadvantage. 

Bravo to Guido for his work on this!  I am sure Guido will appreciate
reports, both positive and negative, on this new version.  One comment
from me: is it possible to change the font in the commands window, as the
default looks ugly on my machine? Did I miss something?
