A feature I suppose. At least, it was a deliberate design choice. The
purpose of cpphs is to remove all # directives from the file, leaving
only Haskell (or plain text if you prefer). Now I realise that this is
not entirely true, since cpphs _does_ leave #line droppings unless you
specify the --noline option. But although most Haskell implementations
do read and use #line hints, I was not aware of any tools that make
further use of #pragma, and indeed quite the opposite - many tools break
if they see the latter.

I am happy to add an option (--pragmas maybe?) to preserve #pragma if
there is user demand. Check the cpphs darcs repository at
http://www.cs.york.ac.uk/fp/darcs/cpphs
for new patches.
