No it did not work (but thanks for it anyway). The problem here has two 
sides, first we seem to end up with the same function listed twice in 
different def files. Your patch tried to fix this, by doing a unique 
sort. But the functions have as a second column an ordinal number and 
these most likely are different. I tried to work around this, by just 
taking the first column into account for the unique test, but for some 
reason this did not work as expected.
But there wer other problems with the patch, it lead to def files that 
dlltool could not process and there were also duplicate ordinal entries 
in the file. That is different functions did get exported with the same 
number.

I don't have any idea how to resolve all these. It also seems not that 
relevant, as we all hope to have a working version of the new export 
handling code for Cygwin in the near future.
