[nhc-users] default heap size

Yes, when you compile a program, you can give a default heapsize for
that program on the command line, e.g.

    nhc98 -o Main Main.hs -H10M

If you want *all* programs built by nhc98 to get a larger default
heapsize, then you can re-configure your build of nhc98 as follows:

    ./configure -H10M
    make runtime
    make install

(Provided you still have the rest of the build on disk, this should
only rebuild the helper utility 'nhc98heap' which does the default
settings.)
