[kaffe] Cygwin status update

[Dalibor Topic]

hi all,

I've been playing with Cygwin & kaffe last week, and I've got patches to 
gradually merge in, that let kaffe build again as a static binary. It 
doesn't fully work, as the kjc step to build rt,jar crashes. 
Investigation about it shows me that the old findJarFile bug still 
strikes on Cygwin. This time I was able to figure out a little more, though.

The problem seems to be that the first few bytes of the findJarFile 
function in kaffe/kaffevm/jar.c somehow get overwritten. I've tried to 
debug it with awatch in GDB, but didn't suceed in catching the 
overwriting happen. So I'd be glad to hear tips & tricks on dealing with 
that type of bugs from other developers.

cheers,

p.s. I haven't attacked the signal context problem yet. I want to merge 
in the patches I have now first.
