# The ghc compiler does normally split the generated C 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
#    http://mail-index.netbsd.org/tech-pkg/2006/07/30/0005.html
# for a description of the problem.
# Disable file splitting until pkgsrc has been improved.
