script to cleanup remove extra space and (void)

[Max Okumoto]

Hi Douwe,

I wrote a script to remove those unwanted spaces and (void) casts.
Since you suggested removing the (void) casts from the make code
I thought you might want it too.

#       o remove space between function name and parameters.
#       o remove (void) cast
#
# Output from nm of the final binary executable is used to generate
# a /bin/ed script, which fixes the problems.  The final executable
# is used because it should have most of the symbols.  CPP macros of
# course are not found in the executable, thus they are not handled.
