-package-conf flag makes runghc fail

[fons]

I haven't been able to test this with 6.8.3 or HEAD but it seems that runghc doesn't work properly when the -package-conf flag is provided.

echo [] > foo.conf # empty package.conf file
echo 'main = putStrLn "foo"' > Main.hs
runghc -package-conf foo.conf Main.hs # this doesn't work
runghc  Main.hs # this works

You need to tell runghc that foo.conf is a GHC flag, and not the program to run:

$ runghc -package-conf --ghc-arg=foo.conf Main.hs
foo

This certainly works in 6.8.3 (and the HEAD), but I don't remember if this flag was in 6.8.2.

This flag is not documented in section 4 of the ghc manual.
