# directory as PrelMain, the compiler will assume that they
# reside in the same DLL as PrelMain & generate code accordingly.
# 
# So, we copy out PrelMain.lhs to ".." and build it there &
# copy the gen'ed object file back in again.

# Note the patsubst hack (see fptools/mk/target.mk and search for
# odir for details)
