This appears to be a genuine conflict between the struct tag in signal.h 
and the one in sid/component/bochs/cpu/fpu/stubs/asm/sigcontext.h. I 
suspect that _fpstate has recently been added to the cygwin header. I'll 
forward this problem on to the author (who probably no longer reads this 
list) and to get his opinion on renaming the one in sigcontext.h

This one I can help you with. I've committed the attached patch which 
should correct the problem.
