Well, that, and there's also the point you graciously didn't make, that 
LD_LIBRARY_PATH has nothing to do with header files anyway.  :)

I agree that LD_LIBRARY_PATH is a red herring, and I should have made it 
clearer in the original post that I thought the real problem was a 
missing package, not that it needed to be manually set.  I'll still bet 
that the problem is that the original poster hasn't installed all of the 
relevant Cygwin GMP packages -- but part of that bet is that I vaguely 
remember having similar problems myself with thinking I'd installed 
everything and then finding I'd missed one of the packages.
