# Build an unregisterised bootstrap compiler and install it directly
# into the .buildlink directory. But we can't use "make install"
# because we don't build it in a standard way (./configure && make).
#
# To install it, we search for any non-symlink executables in
# work/ghc-6.4.2 whose name ends with "-inplace". Then copy those
# files into ${BUILDLINK_DIR}/bin with dropping the "-inplace" at
# their tails.

# 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.
