Hi,
I guess you're using beta18 of the cygwin.dll, which will not work with
2.02.
The exception is due to a change in the floating point code generated by
the gcc snapshot used for beta18 compared to the one we used when
doing 2.02 (beta17). The list of exports for the cygwin.dll might not have
changed between beta17 and beta18, just the calling conventions for
some of the entry points :-(
I've "fixed" this problem and a couple of others, and should have a
binary snapshot of 2.04+ out within the week.
Thanks for the report,
--Sigbjorn
