RE: GHC doesn't doesn't clean up the way it should

Yep, the temporary file is still there. The funny thing is that this doesn't
happen with all files. In my little test case with two Haskell modules only
one of them gets a temp file left behind. What more information can I give
to help you track this one down?

Thanks for the pointer to the documentation!

Does it really leave the temporary file behind?  I tried it here and it
deleted the file.

The syntax of the command line is documented under the -pgmF option,
which you may have missed because -pgmF is documented in two places (I
just fixed that).  See here:

tml#PRE-PROCESSOR
