Wow - sorry if this came across as an insult.  I was debugging after a glass
of wine myself, and that was not my intention.

I managed to build a working DLL by tweaking the above objcopy commands to 
conform the results to the stock DLL's headers.  I don't know why the perl
script is getting it wrong.

objcopy -j .stab -j .stabstr cygwin0.dll cygwin1.dbg
objcopy -g --add-gnu-debuglink=cygwin1.dbg cygwin0.dll
objcopy -R .gnu_debuglink_overlay --set-section-flag .gnu_debuglink=contents,readonly,debug,noload --change-section-address .gnu_debuglink=0x6115f000 cygwin0.dll

I'll post when I have some results regarding the x64 slowdown.

Regards,

David
