many years ago I got sick of porting such code to a machine with an
ANSI compiler - the important error messages got lost in all the noise...
So I wrote a little script to fix C preprocessor directives...

These days I use a generic sedem script (run sed, check for change if
so save old file etc) and a simple file containing the sed command
from the earlier script.

Since I find sedem very useful for many bulk editing tasks, others
might too, so here it is...
