The "shortc" program posted a while ago is very nice, if you
have a preprocessor that can handle long identifiers.
If you don't, then use m4 with a macro file generated by the
following modification to shortc:

194,195c194,195
< 		    printf("#define %s %s%s\n", y->inname,
< 						y->prefix, y->inname);
---
> 		    printf("define(`%s',`ifelse($#,0,%s%s,%s%s($*))')\n",
> 			 y->inname, y->prefix, y->inname, y->prefix, y->inname);

At the end of the m4 macro file include the following text:
(either put it into the end of dump() in shortc.c, or add it
after the rest is generated.)

changequote($$#$$,##$##)
undefine($$#$$changequote##$##)
undefine($$#$$undefine##$##)
/* This is a dummy line for sed to rip off */

(i.e. for file in *.[ch] do ; m4 short.out $file >tmp && mv tmp $file ; done)

Thanks to Tony Hansen for this one.
