Hi Linus,

Oh, I see, that's because traditional seds require a newline before
a closing brace. Rewriting it as follows should work:

1{s/\/\*/@comment  /

(You'll have to put it into a separate script, since make will not allow
embedded newlines in a command, and replace the Makefile.am rule with
.c.inc:; sed -f SCRIPT_NAME $< > $@). Please let me know if it works, so
I update the CVS accordingly.

I guess sed is better and simpler. After all, both sed and awk will
require a separate script, so we won't gain anything by using awk
(except producing extra memory hog).
