One more quick follow-up: It seems that I need to add a "return(0);" line t=
o my main routine to get any C examples to work under Windows, whereas I do=
n't need to add such a line on my Mac. I just tried the cocktail.c example =
from your 2012 Journal of Statistical Software article, and this works on m=
y Mac, but fails on my PC (even with my edits to ob-C.el) unless I add "ret=
urn(0);" at the end of the main code block.=20

It would be nice for Windows users to be able to run others' examples witho=
ut having to edit them first, so what do you think of the idea of having  o=
b-C.el append a "return(0);" line to the main file before passing it to the=
 compiler?=20
