# Unregisterised HC packages are platform-dependent C sources. Yes,
# they are C sources but are totally non-portable. We have to create
# more HC packages to support more platforms. Note that those packages
# are built with integer-simple, not integer-gmp, to reduce some
# complexity by not depending on the GMP. The resulting registerised
# GHC uses integer-gmp so this won't be a problem.
#
# If you want to build HC packages yourself, follow instructions in
# the ./TODO file.

# The ghc compiler does normally split the generated asm files into small
# parts before sending them to gcc, to enable the linker to eliminate
# unused parts.  This does however not play nice with the pkgsrc
# framework, and the result is that the build takes more than 5 times
# as long than when the files are not split.  See
