[nhc-bugs] Error compiling nhc98-1.10 in Linux

Ah, that is unfortunate.  Some of the hat tools (hat-observe and
hat-detect) must be compiled with nhc98, but the hmake in your build
tree does not yet know about the fresh nhc98, because hmake was
configured _before_ you built nhc98!

A workaround is:

    make install	# install the fresh nhc98
    script/confhc	# detect compilers again, including the fresh nhc98
    ./configure		# propagate the new hmake configuration
    make all		# finish off the build (just the hat tools)
    make install	# and do the final install

For the future, I shall try to think of a clean way to enable hmake
to have automatic knowledge of the fresh nhc98 in the build tree.
