haskell-src-exts doesn't include a CPP processor no, but will discard
all lines beginning with # (as an old hack to allow #!/bin/runhaskell
style cgi-files). This of course leads to the kinds of problems you
suggest with #if conditionals. So if you want to really support files
with CPP you need to run a separate processor first, like cpphs as
Malcolm suggested.
