Thanks, this was pretty much exactly what I was looking for, but it turned 
out the builds at are so outdated that the option does not exist 
(-fdebug-prefix-map=/cygdrive/c/=C:/ resulted in an error at least).

I managed to create a really dirty workaround for now which was to create 
C:\cygdrive and then symlink/mklink 'c' => 'C:\' which appears to work but 
is extremely ugly. Still open for suggestions.

You may be able to use GCC's -fdebug-prefix-map option.
